I looked back at the results from October, and the difference in times was pretty huge for a number of people.
I did a 52.4 in Oct, and managed a 50.3 yesterday (with absolutely no change to the car between the two–still running on 5 1/2 cylinders both times). Some of the difference was definitely from already having a bit a familiarity with the course. I think that taking that Evo School Phase II back in December helped too.
Anyway, times aside, the event yesterday was a ton of fun. Thanks to everyone for helping to make it a success!
