It is possible to randomize player's performance as well, see it as "perturbation" for player. AI was too slow in Moto 2, just made 5 different MOTO2_TOP files (because "Gresini Federal Oil" is a TOP bike). Each contained a different value for bike's weight - 150, 160, 170, 180, 190 kg! Understandably I tried to ride 190 kg, and it was slower ~ 3 seconds per lap, than bike having 140 kg mass! So player himself can be slowed down, no "AI too slow" problem. More: made 5 files + filename randomizer, all 5 filenames are randomized - names are just a bunch of numbers, choose any of them - and put in data folder, renaming to MOTO2_TOP.BML, of course, in my case, and voila! Nicest thing is that you will not know before the race (or qualifying) what value is in that file! You will get a clue at the start, when acceleration will be an indication, how "team mechanics" have worked... Of course, mass\weight is just most primitive thing, other things can be changed.
