The most popular weekends up here are doubles/triples that look like this:

Sat AM qual
Sat PM race
Sun AM qual race (grid based on Sat PM fast lap)
Sun PM race (grid based on finish position from Sun AM race)

Schools, test days and most HPDE clubs provide much better value for 'track time'. Race weekends should maximize RACING.

Inverted grids do not reward the fast drivers (isn't that what this is about?) and puts slower drivers in a situation that they don't need to be in so early in the race.
