P2 finish and you got faster as the race went on (-0.47s trend) — that's exactly the direction you want, means you were still finding speed on lap 10. Sector 3 was your strong point all race, so keep doing whatever you're doing there. Your opportunity for next time is sector 1 — you're leaving 0.24s per lap on the table, and it's all sitting in that sector based on your own best times. Tighten that up and you're looking at a solidly quicker average lap without changing anything else.
