That could actually end up working against you twofold, especially on BL with the long straight. I'm going to go ahead and guess the record laptimes are going to be set on a day with a strong tailwind.
I think I thought the same thing as Mike -- you get points for the race results, period, and additional points for your best (or average?) laptime. So here's my suggestion (though now that the system is live it might be a bit late..)
Points are based on finishing position, number of cars and number of laps. Multiplier for being 105%ish within the fastest lap of that race. Additional points for being within 106% of record time, with maybe a max of 10 points.
It also seemed like longer races gave you too many points (or in my case, short races were too few
) I probably got at least 80% of my points on endurance days. Maybe take the square root of number of laps instead of scaling linearly.
