Solid finish today, P4 with laps that kept getting better as the race went on — that -0.74s improving trend shows real focus late in the run, which is exactly when it's hardest to find. Sector 3 was your best work; you were clean and repeatable there all race. Your next gain is sitting in sector 1 — you've got 1.56s per lap available between your best lap and your ideal lap, and most of it's hiding there. Go into next race treating sector 1 like a puzzle to solve, and that 39.78 becomes your new normal, not your ceiling.
