Quick note-
Here's a 20 minute vid of me at Road America. Sorry for the bad lighting, my fault, didn't configure the camera right- put it on center weighted metering instead of spot metering.

Feel free to critique. You will be able to tell which corners I'm actively giving up for safety (for me or the people in front) but you'll also be able to see how much speed many drivers scrub off before a turn, over slowing their cars.
I didn't even bother adjusting tire temps- they rose from the doorjamb recommended cold 29/34 psi to well over an indicated hot 38/46 psi from the beginning of the sessions to the end. Michelin specs call for a 32/26 psi hot pressure, I'll worry about that when I'm getting closer to the edge.
