PreQ system works very well in a huge brazilian League, where we had tons of signs.
Basically we had a division A and B.
This is sorted by a PreQ system where every driver have to do 10 consecutive laps (12 in total, 10 valid ones), and their average speed is classified.
Top 25 or so go to division A, the rest race in the division B.
This is very good because drivers of similar skill levels have the chance to race together, making overall racing better.
Also is good because is not about hot lappers. Is about put a string of laps together, with consistency.
Is mandatory all drivers put a average time on the board.
Of course I think there are some programs that you can put in place that will catch up our average times and can be publish here.
yes that could work quite well.
