F1 2011 How do you choose a correct race strategy?

[Camacho]

Hi all friends!

I'm doing a 50% race distance season and in most of the races the engineer select a 2 pit-stop strategy using:
- Start with option tyres used in qualifying
- First pit-stop and put prime tyres
- Second pit-stop and put prime tyres

In these cases I change the strategy to a 3 pit-stop race using:
- Start with option tyres used in qualifying
- First pit-stop and put option tyres
- Second pit-stop and put option tyres
- Third pit-stop and put prime tyres

In most of the races I win the race but in the last race in Silverstone the strategy fails: A 2 pit-stop strategy seems to be better.

My question is: how could I sense what strategy should be better? 2 or 3 pit-stops?

And why the engineer in most of the cases selects a 2 pit-stop strategy and the AI cars always do this strategy too?

Thanks in advance and a very happy racing from Spain!!

The pit lane at silverstone is massive if thats any help.

As the post above suggested, you have to take the length of the pitlane into consideration so you know how much time your losing compared with the length of time youll gain with the fresh rubber in the stops.In a 50% race, 2 stoppers are the norm because the tyres only really wear out enough for a 2 stop, apart from the red super softs but even then I managed to 2 stop in Canada in a 50% race and the suggested was a 4 stop lol

The formatting is screwed since the move to the new website, but there is a thread giving the pit timing. The 1st number is in the DRY and the 2nd is WET timing.

At Silverstone the pitlane lenght isn't as much of a disadvantage as you might imagine, it bypasses a couple of slow corners. That's why we saw stop-go penalties rather than drive throughs at the real race this year.
