Well an easy race to monitor pit stops is the 50 laps at Super Speedway. That one is easy to win. Something interesting I have noticed is to watch the time gap between you and first place (or second place behind you) after each checkpoint. I have noticed substantial changes in time when the AI cars are getting close to pitting. I used that to predict their pitting laps.
One example was when I was racing Grand Valley. I had 7 laps to go to complete the race. The F094/S was way ahead, but I was catching up to second place, which was an F094/H. They had about 2 laps before their last pit, I was like three laps on my new tires. So I was smoking the clock, quickly catching the front 2 cars. Of course I couldn't make up 40 seconds within that remaining 6 or 7 laps. So I decided I would get the second place car. I caught him, then pitted again right in behind him. I knew I wasn't going to make it to the finish with my tires I was already on, so I pitted with only 3 laps on my tires. I done this because I had already discovered that my pit lane was directly in front of the F094/H. So he pitted in front of me, then I pulled in right in front of him. Once he was done, he got stuck behind me until I was done. This gave me second place coming out of the pits, so I didn't have to battle him except about half a lap.
After that, I just closed up as much time on first (knowing I couldn't catch him anyway) just to see how much time I could make up. My lap times were better than every other cars' lap times, but I get one less lap than they do, so I am basically screwed. Oh well, I will figure something out eventually.
Good luck on F1 Monaco hell! Sounds like a definite challenge. Later!! :burnout::burnout::burnout:
