Sorry to say it all seems a total nonsense to me and can't see what advantages it will bring. Although the championship is not the all to end all, it does add a little spice to the club racing. So why allow half the season racing for nothing, the only ones that gain any advantage from this are those racing both classes. If you don't want it to be an attendance championship, then make it the best 18-20 scores out of the 26 rounds.
Don't agree with the F1 scoring system either, sorry LR. Although in principle its a good idea and works well in other race programs, it doesn't suit our club racing as those at the bottom would never get any points and they as much as those at the top, want to finish the championship above like for like racers. A lot of championships give an extra point for FTD, why don't we take it a little further and give an extra point for winning your final, which would be yet another incentive for those down in the C or D finals.
Sorry if I sound a bit negative, but I think it could be done better to suit everyone
Could someone point me in the direction of the GERCC’s own GT12/Mardave rules, as I'd be interested.
