Not exactly sure on laps (cant be bothered to check) i've done about 300, and my pb is 1m02s04. I dont think laps really has any relevence though, a lot of my laps at that track where when I was new and turning in to early, braking too softly, and getting on the power too late (and doing 1m03's incidentally).
Now i've learned the game more at other tracks and i've started doing this combo again, and I instantly knocked a second off my old pb in the first few laps. A quick setup tweek tonight and i'm now regularly getting low 1m02 times in a car i'm comfortable with driving and barely ever making a significant error, this makes me reasonably competetive and puts me on the rostrum quite a lot, not least because whatever my lap times i'm something of a dogfighter. My key failing atm is confidence in T1 as I keep loosing 4 or more places.
If you want to check progress log onto a full grid, do half a dozen races, and see where you end up.
Don't worry about how many laps you've done at that track, but how many laps you've done in a Fox and in LFS in general.
I've been playing 4 months and am quite a frequent player, so I guess my progress (nipping on the heals of the ninja's) is ok. Put me in a car other than the Fox and i'm nowhere though, so my progress is poor.
