[MustGoFaster]

AS many as you want! The most I have heard of anybody doing is 47 runs. After that, you just get bored an stop, even with trading cars. To put that in perspective, a full year of AX runs is 54 (9 events, 6 runs each) In the morning, the lines can be a little long. But in the afternoon, there were a number of time where, as people pulled up to the line I told them "go when ready" (I was the starter for one course)

I did 11 runs. 8 to learn a new car and R comps. 3 in an STS Miata. I tried to find some other cars to drive, but felt a little uncomfortable going up to people I didn't know and asking to drive their car, so I didn't ask a ton of people.
