Thinking about Randy's 2:24 (actually, he was down to 2:23 this past weekend) compared to my 2:30...
Looked at my split report with the last two Sunday sessions loaded up. Lo and behold I have a theortical best time of 2:24.709 using my best individual segment times from among the 15 laps in those two sessions. Actually, only 5 laps contributed to the theoretical best time, and three of the seven segments came from a single lap. So, maybe I'm closer to a decent lap than I thought--just have to string all the good segments together into the same lap.
Gotta love data acquisition: improved lap times and self-image at the same time!
