Has anyone worked out a calculator or something for determining fuelusage for rF (or any of the other sim's) tracks? I read somewhere a while back that track distance x 14 (or16 or perhaps it was 18) will give the answer, but Ive personally found that that sum does tend to over fuel a car on longer tracks with the AI going for another lap they never make or to pull in on every lap & that up beyond 30+km's I can virtually get away with just rounding the distance up & adding a zero onto it before the decimal point as fuelusage doesn't seem to be a linear calculation. Although this method is not precise & still requires, at times much, experimentation which can become quite tiresome with tracks around 50 to 90km's in length..... Especially when the next time out in a different car mod, that hasn't had it's own fuel figures properly calculated, causes a serious rethink on the last figure attained.... Any information or thoughts on this would be greatly appreciated, thank you. (edit) Also, is there someway of making the AI cars 'gear up' their ratio's for higher speed circuits, & I suppose, lowering for tighter/slower circuits so as to be more competitive after having done that for my own car? I'm wondering if it's possible to do this within the tracks AIW File much like adjusting the fuelusage figure?
