Great runs! For having a 91/94 mix - these are pretty solid ET's. The MPH is on the lower side - but still solid. I would suggest 94 octane - no mix. Was the track day just a test and tune, limited prep? The reason I ask is because the 60' for Michelins was pretty high for most of your runs. You bring it down to a low 1.7 or high 1.6x and you will see 11.0's.
