Different race Times for Rookie and Pro: So this would work so that owner of the league if he wants can put Rookie and Pro race 1-2 hours earlier than Elite races. Now i think its a good idea and i think its not that hard to make it to work in game and of course owner will choose if he wants to put Rookie and Pro races before Elite...
I will give an example:
Elite race - 8:00PM
Pro race - 7:00PM
Rookie race - 6:00PM
Also time beetwen racee can be also 2 hours this is an example with 1 hour difference beetwen races
