So what does Random Grip Range in GP2Edit I havent edited it yet and is on 500, what its mean What will do more or less value because I havent test it yet
Well, the Random Grip Range is a certain value which reduces the normal grip of your driver whenever a new race is calculated.
Let's say for argument's sake you have two drivers:
Rubens Barrichello - Grip: 16000, Random Grip Range: 1000
Ralf Schumacher - Grip: 15500, Random Grip Range: 0
When you start a race weekend in the game, a certain number between 1 and 1000 is reduced from Rubens' grip so during the weekend it could look like this:
Rubens Barrichello - Grip: 15900
Ralf Schumacher - Grip: 15500
or like this:
Rubens Barrichello - Grip: 15000
Ralf Schumacher - Grip: 15500
So the Random Grip Range is simply a value which determines how consistent a driver's grip is. If you have an erratic driver which is "god of racing" on one day and horrible on other days, you should take a high value. If you have someone who drives like a machine, you should take a low one.
Personally I go for smaller values, due drivers are pretty constant and the races are more challengeing, due the drivers keep being faster. In modern carsets with close field gaps, even values of 100-200 can have an immense effect
Calculating laptimes into grip values isn't the problem.
I calculate it with openoffice calc (comparable with microsoft's excel) and with the race performance calculator.
Don't know if it's the right way, for me it worked.
But I want to know what the actual grip values are of each driver for each sessions.
So that I could see how random the random grip range works.
I don`t know if GP2Lap also saves the laptimes in trainings or something similar, but using gp2perf you should be able to get each drivers best laptime for each session, provided you save each session at its` end
