(Non)-competitive Logic

...and what to do about it

Yesterday, we saw Force India choose to not run in Q3 at Singapore. This is the second time this season they have taken this option. In DRStrategy, this was recommended as the solution for a team which cannot seriously compete for pole in Q3. There was no possibility of Force India managing a much higher position if it ran than if it didn't, so it was sensible to save a set of tyres to preserve strategy and perhaps pass the more profligate Mercedes team through strategy.

 

This may seem a rather mercenary attitude, but remember Force India is in a battle between Renault and Sauber over 5th place in the championship. Sauber is very close behind Force India, so it needs points. In addition, Renault is having a lousy weekend in Singapore, making this the best opportunity Force India is likely to have to close the gap between the two. Logically, Force India has to prioritise racing well to qualifying well.

 

So all is well? Not to judge from the large number of disappointed fans. The best I've seen of their reaction came from @LewisBarthaud:

 

something needs to be done, this 3 phase format came about to improve the show, you can't call it the "top 10 shootout" with only 7

 

You can't argue with that logic. Also, there's an emotional argument which presumably wouldn't condense into the remaining characters.

 

There is a massive visceral pleasure in seeing a racing car on track. When there are many racing cars doing likewise and competing powerfully with one another, the pleasure is multiplied. So to take it in reverse, removing 30% of the expected competitors will take out an average of well over 30% of the excitement (exact percentage depending on exactly who "forfeited" the session and who's watching).

 

This is an example of perverse incentives - the regulations, designed to provide excitement and happiness to the multitudes who watch F1 racing, create the exact opposite effect in qualifying if played out to their logical conclusion.

 

The first thought might be to penalise those who do not run in Q3 on purpose through a grid penalty. However, this ends up creating perverse incentives of its own. One of the main ways people have been able to overcome the zero-sum passing engendered by DRS is by having more sets of unused soft tyres. What this means is that everyone will, barring unforeseen punctures or crashes, everyone will have the same number of sets of soft tyres remaining. By insisting everyone must have the same number of unused sets of soft tyres, the racing will become even more predictable and samey - under the rippled surface of inconsequential passes. Only someone setting their fastest time with hard tyres will be able to break the cycle.

 

So that method of making a more exciting qualifying would make a rather dull race. However, this is not an insoluable equation. Changing the way tyre allocations work may help.

 

My proposal works thus:

 

- 3 "hard" sets given out on Friday. This will encourage race set-up and endurance work, shift tyre comparison work to Saturday, possibly encourage more teams to use unproven drivers. More importantly for the specific problem under discussion, it means a "soft" set can be awarded later in the weekend without making Pirelli bring any extra tyres. You've got to adapt to cost-cutting...

- 1 "soft" and 1 "hard" tyre set given out at the start of Saturday

-  1 "soft" and 1 "hard" tyre given out at the start of Q1. Any of the three sets of softs given out thus far may be used in qualifying.

- 1 "soft" given out at the start of Q2 - but only to drivers who set a time on the soft given out in Q1.

- 1 "soft" given out at the start of Q3 - but only to drivers who set a time on the soft given out in Q2.

- 2 "soft" and 1 "hard" set given out on Sunday - but only to drivers who set a time on the soft given out in Q3 (or Q1/2 if they were eliminated there). Q3 runners will be permitted to use this instead of the tyre they did their time on, should they be eligible to receive such tyres. Teams will hand back 3 "hard" and 2 "soft" sets of their choice, leaving them with the same number of tyres for the race as they have now.

 

Stewards' discretion will be used for anyone who makes a genuine attempt to qualify but has a technical issue on-track, crashes on their "sighter" Q1 run on hard tyres or during their soft-tyre run. The idea being that genuine accidents would be treated the same as people who were knocked out at the same stage but completed the soft-tyre run. Anyone of whom foul play is suspected (or had such serious problems that they  wouldn't have used up much/any of the soft tyre's longevity) will receive no such privileges and be treated the same as those who never attempted the run.

 

This would mean qualifying would influence how many tyres on has available in a more sensible way.

 

  • Someone who didn't run in Q1 on soft tyres would have no unused "soft" tyres.
  • Someone who chose not to run in Q2 or Q3 on soft tyres would have 1 set of unused "soft" tyres (the one they got for running in Q1 on softs).
  • Someone who chose to run soft tyres in all sessions for which they were eligible would get 2 sets of unused "soft" tyres (for running in Q3).

 

 This should re-align incentives for the race in favour of having both an exciting qualifying and an exciting race.

 

The one thing this doesn't prevent is a team not running because they don't think they will lose anything, despite the disincentives in place. This is the frustrating position I am in with my other favourite team, AF Corse. It is in Portugul for the Le Mans Series race but due to some terrible luck involving a lorry accident, a broken tail-lift and an hastily-completed new car presenting problems, is apparently comtemplating a deliberate non-finish for its hitherto most competitive and popular car (the #51 driven by Giancarlo Fisichella and Gianmaria Bruni). It's already team champion, with the #51's drivers also confirmed as individual champions, so they not particularly worried about points. The car is in one piece and is very fast when it works, but could break at any moment and the staff all need to be in America as soon as possible because Petit Le Mans, part of an Intercontinental Le Mans Championship that the team hasn't fully secured yet, is next week and everyone on the the team needs to be there for early scrutineering. I can see the logic but am still upset with the idea a team might forefeit a race where it has somehow managed to qualify 2nd. Much as the people watching the logical withdrawal of the Force Indias from Q3 were upset about them "forfeiting" the last bit of qualifying when they were good enough to at least set representative times. 

 

Intellectually logical, emotionally tough to accept...

This entry has taken me some time to figure out how to write. Something's been bugging me about recent F1, primarily since the Turkish Grand Prix. However, it was only when Duncan Stephen wrote his item on why he was finding 2011-spec F1 not to his taste that I figured out how to write my own objections to what's been going on. My first reaction to the piece was:

Hurrah! Somebody doesn't think that the current F1 is a) the bee's knees or b) only ruined by excess overtaking.

For me the proximate problem (i.e. the one that's directly causing me dissatisfaction with F1) is meaningless overtaking. In Turkey in particular, the method of generation of overtaking caused lots of zero-sum exchanges - lots of passes but most of them were never going to affect anything in a month of Sundays. They were just going to get re-passed later in the corner sequence or else in the DRS zone the following lap.

DRS foreshortens the process of passing even when it's producing a reasonable net increase of overtaking. This makes it less skilful and also less significant in the context of a race. Those comparing Turkey 2011 to Japan 2005 have forgotten, among other things, that many of the overtaking moves in the latter took laps to set up. Yes, it was normal for cars to be innately 1-2 seconds faster or slower than each other that year, making things difficult enough for complaints, but that still shows planning and skill were important.

If pressing buttons is the new hot skill for F1, why aren't all the F1 drivers being sent on evening typing courses? Why aren't fit typists with clean driving licences being considered for F1 testing roles over the heads of those who have toiled in F3 and GP2?

Besides all that, DRS should never have been experimented with in a race weekend. It should have been tested properly prior to use, and then implemented equally and effectively in all races.

Despite the emphasis on changes to the racing, qualifying has now become the be- and end-all of F1. The only reason it's not become the only non-accidental deciding factor is because many teams haven't worked out it's merely a question of getting your single lap per session faster than those around you. It's no longer possible to waste tyres doing two runs. If you're first into the first corner, DRS means you'll be able to pull out a big lead and protect your tyres as you will while everyone battles behind you. I felt like kicking Lewis Hamilton and Jenson Button when they did their little duel at the start; by focusing on each other they lost time to Sebastian Vettel and wore out their tyres, which made it impossible for either to do anything about the race leader.

That's right, to get exciting racing for the lead in this system you need a team to qualify both its drivers right behind the lead one (without the pole-sitter's team-mate or any other team being in between) and then execute firm team orders on lap 1 to stop them from attempting to race each other. The "no. 2" would be tasked with staying 1.1 seconds ahead of 4th place and then keeping a consistent pace to remain 1.1 seconds ahead of 4th place, preserving the invisible barrier. "Good" thing systematic team orders are permitted this year, else every race win would be unsalvageable.

If you're not a potential race winner, qualifying is still vital and still has to be done as a single-lap run for each of the three sessions. This would be one set of tyres for Q1 and Q2 and then a second set for whichever session is believed to be the final one. If you get through to Q3 when it wasn't expected, simply sit out the session to preserve your strategy. This is because if you can't look after your tyres, the best strategy is to have as many new ones as possible. If you can do that, it's irrelevant whether you can pass the people around you (with gimmicks or not) because you'll probably gain a pit stop on them - especially if your car is relatively kind to tyres like the Sauber is). Even if you don't, you'll gain considerable amounts of time and flexibility.

It's bizarre that the strategies dictated by fragile tyres and ease of DRS-based tactics mean that the act of passing - DRS-based or otherwise - is almost irrelevant to the results.

The trick is to evenly space out all tyre changes according to when your car will need them, which should be quite straightforward to determine based upon performance in the first stint. It doesn't even need anyone to bother doing a pre-race equation - it's simply a question of chucking tyres at a car when it needs them. Pit strategy outside the options a car may deny has now got so little relevance that the discretionary laps can be deployed whenever the team wishes. All the strategy divergence is down to two factors: a) due to the tyre philosophy being new, different cars treat them very differently and b) many teams do not appear to have figured out what's going on yet, so haven't even taken the obvious step of going single-lap each session up to this point.

So we now have the single-lap qualifying some people have called for. It's not improving the racing - it's taken it away. Duncan Stephen has called it "one step away from fixing the result". I wish I could be so reserved on the matter. As far as I can see, it is fixing the result to whoever happens to be the fastest one-run driver/car combination in qualifying, and for most of the top 10, stupidity and extreme tyre wear permitting, they are fixed in the positions in which they qualified.

KERS doesn't seem to do anything to help the sport - it just seems to be something tagged on to keep the stupider elements of the environmental movement a little more content. It's in F1 in a form that will never be utilised on the road (road KERS will be a very gentle addition for all accelerations, not a big boost done occasionally), delivering power in a way that makes overtaking more difficult (which may be protecting us from even worse problems with DRS) and with a lack of freedom which places it firmly in "gimmick" rather than the "feature" it is about to become in sportscar racing. That it's not facing a campaign for removal at this time shows just how much of a problem DRS presents.

One of the things which worries me - and I think it's one of the things that's made it difficult for me to blog - is that so many people don't seem to see the medium-sized picture let alone the big one. They see lots of passing, lots of energy, lots of confusion - and start cheering. They do not see that it's causing very predictable strategies, very predictable results and a very samey feel to races. Energy and confusion might have got many into the sport but if it had kept being those things at the expense of everything else - especially the surprise element - they'd have stopped watching within a season because there'd be nothing to grip them with. If I wanted to know the winner 24 hours before the race and the result of a race for most of the field on lap 15, I'd put on a season review DVD. At least then there'd be decent camera direction...

Sport is a form of entertainment. If done properly, it will be entertaining whether or not the "show" is considered (the "show" only affects how many people get entertained and the length of the entertaining). The decade-long trend towards considering "show" over "sport" is nearly complete. But F1 is not reality TV. Reality TV tropes do not necessarily work for sports such as F1, even with extreme tweaking. The cost is that F1 will soon be unable to be called the pinnacle of motor sport, on the grounds that it will not be a sport at all. The sport needs urgent attention in order to save it, to take away the worst of the gimmicks. That way it might be possible to see how to get the enjoyment of racing to run clear again.

Though I'll let the powers-that-be tweak the "show" enough to get a competent TV direction system and crew. The current one hasn't worked since FOM took over the job and 2011 is exposing their weaknesses so much. It's even more frustrating to be watching a predictable race when perfectly competent commentators, used to having at least vaguely usable images to commentate from, find themselves clueless to things you figured out 30 laps before because you, unlike them, could see the little ticker-tape running across the bottom of the screen...
