Update: Improved to a 1:15.426, that pushes me to upper C. I'll take it, I could've been better through Ascari and Parabolica but it was a really good lap. I saw a couple of R$ One:1's in the Top 50 of C but I think this is the best I can do.
Found 4-tenths through Rettifilo, and then another 3-tenths through Roggia. Then held it through the rest of the lap, about par to my previous lap, which was really good from Lesmo onwards. Despite a couple mini-skids, I did find some hundreths through Ascari and Parabolica. I'll take the lap, was a very good one.
