In most cases (dry weather races) the common pit stop strategy appears to be, start on options if you qualify well and then switch to primes 25-33% through the race distance. Likewise start on primes if you do not qualify well and switch to options 66-75% of the way. But after thinking about my race last night at Silverstone I am now wondering if anyone has been successful using a 2 stop strategy. I don't think 2 stoppers makes sense for those people who do short races, but for those of us who do longer 100% length races, I wonder if they can work? Using an HRT I qualified in the middle/rear of the pack at Silverstone and I started the race on primes. But most (possibly all) the AI cars in front me started on options. Using the True AI 1.4 mod racing against "Pro" AI, I could not keep up to the cars in front of me who were on options. However as soon as I switched from primes to options, I became competitive again on the track. But there was too much lost ground to make up. So I was wondering for tracks without long pit lanes, and when you do not qualify well, if starting on options driving like hell, and then having a two stop strategy where you spend most of the race using two sets of options and only one stint on the slower primes has worked for anyone?
