Good point! So here's the schedule...

1. Arrive at track
2. Measure rotors and pagids, install pagids
3. Bed in pads
4. Run 2 sessions
5. Measure rotors and pagids, install ST pads
6. Bed in pads
7. Run 2 sessions
8. Measure rotors and ST pads

Too bad we don't only have one day to drive.
Yeah but I think the brakes will take about the same amount of beating. The temp difference seems to be about 15-20 degrees ambient on average. I don't think that will make too much of a difference as far as brakes are concerned. As long as the tires can get up to temp quickly.

OK but my tires will look flat when they are cold!
