P3 with laps that got faster as the race went on — that's a great sign, especially since you actually led the field in all three sectors at some point. That tells you the raw pace is there. Your one focus for next time: sector 1 — it's your least consistent, and tightening it up is worth real time, since you're leaving 1.31s per lap on the table against your own ideal of 36.77s. Bring that improving trend from the end of this race to the start of the next one, and P3 won't be your ceiling.
