Hey Luke, nice riding there, buddy!! A couple of things from my perspective.

Your lines are generally very good.... except when you miss apexes. So mostly top marks on that, but work on a bit more consistency with your lines, as being wide on apexes fairly frequently can cause issues where you're expecting the same level of grip as right on the race line, but it's not quite there. Track time is the answer here; practice practice practice!

Most guys short-shift out of T2, just as you transition from turning left to turning right before T3. You're doing T3 in 2nd, which is a bit revvy. Likewise on the back straight between T9 and T10, try grabbing 4th instead of leaving it in 3rd. You'll gain more straightline speed, plus you'll take T10 at a higher speed because the bike can 'flow' on a closed throttle much better at lower rpm. Then downshift when you are upright, as you transition from turning right in T10 to turning left for T11. Likewise, try continuing to only shift down one gear (ie 4th to 3rd, instead of 3rd to 2nd that you're doing now), and take T11 and T12 in 3rd. You'll again be able to flow the bike better, aiming for a higher mid-corner speed, and when you exit T12 at a higher speed, you'll be right at the start of the power band in 3rd for the drive down the straight.

Your crash was very very odd. It just didn't look like it should've highsided. You were narrow on your corner entry due to overtaking the other bike, but still it just seemed you were just a bit too upright to highside like that. Just unlucky, I guess. How old was the rear tyre?
