My tires' grip starts to decrease at around 42psi hot... At autox, I get to "hot" by the 3rd run (less than 5 minutes between runs). I've been starting at 34psi cold, and my 3rd run (of 4) is usually fastest.

Thanks. This is exactly the sort of advise I was hoping to get.
I haven't timed it, but some of our events are so large (130-180+ people) that it's more than 10 minutes between runs. I'd like to think I get faster as the day goes on.
