Nice trend to end on — you got faster as the race went on, improving 3.59 seconds by the finish, which tells you the pace is there once you settle in. Sector 2 was your best work all race, so trust that rhythm. Your opportunity is sector 3 — it's costing you most of that 0.72s per lap gap between your best (40.57s) and your ideal (39.85s), so smoothing that out is the clearest path to faster laps next time out. Take that improving trend as your baseline and see if you can start the race at the pace you were running by lap 7.
