I've never been lucky enough to make it there. Could somebody explain the format .

First two nights are standard USAC show like sprint week.

Not sure if its top four from each night or what but some are locked into Sat Night, Those top cars do two lap races knocking each other out till one gets the poll.

I think it is top 8 in points after the two nights are locked in. I don't remember the point system they use though.

I think its 50 pts. for fast time, decreasing by one, 20 for heat, by ones, 100 for feature, decreasing by 2s. Just looked it up somewhere...
