Updating with the time slips and intervals analysis from my runs at Gainesville Raceway on 23 Nov 2019,

As I had Dragy there I’m also including a comparison of it’s eighth and qtr mile data with the actual slips. On average it’s about 0.02 sec slower than actual in both distances, and 0.16 mph and 0.38 mph faster than actual in the eighth and qtr (although quite a bit of variance individually). Appears to be a useful tool for those who can’t make it to a strip to evaluate their performance.
Would be interested to read what others think about the Eff vs Sport mode data and if it can be reproduced on multiple F97/98s. If I knew at the Strip it was opposite to what we expect I would’ve run a few more Sport and Eff to try to confirm but unfortunately I didn’t have time to analyze while there.
[Edit 28 Nov 2019 - Note the tire psi for these runs - BMW's recs of 33 Front, 38 Rear (will try lowering next trip to see if traction can be improved at launch)]
