I am graving more people to race with in bigger events so why not add the number of people that can join/spec.
Like in westhill (GTAL) is 32 grids so that would make 64 overall connections of players and maybe 6 reserved for admins/commentators = 70
I think 20 cars are tad too few to do endurance with on long tracks

+ 40 car grid

- computors will explode all over the world.. lol xD
