As far as race length goes, I say the outlaws have it right. I've always been been a USAC fan since my dad thankfully took me and my brother and our friends to the races back in the 70s. Pull out a sprint car pictorial from those times and you will see 40 laps were the standard with longer races thrown in as well. The outlaws basically give you 40 on a quarter, 35 on a 3/8th and 30 on a half, makes sense to me.
Often I hear about what people in the office at USAC make, as someone mentioned it here. I've never researched it but maybe someone with knowledge of the situation and facts could start another thread about it, because I would like to know a bit more about it as it apparently puts a thorn in a lot of folks sides
