You make a good point about Apex’s, after I made that post I spent a little bit of time in Circuit tools looking at the Delta-T’s and lines between the instructors lap, my lap and a couple of my other faster laps to see where I was making and losing time.
Looking at the data I definitely am missing a couple of the apex’s, on T2 it looks like I’m apexing too early and on T10 I’m apexing too late. You can see it on the video too since I’m tracking out on T2 with less corner speed than most people and on T10 I’m not tracking out with a much lower corner speed than others which makes it look like there is room to Apex earlier with more speed and track out since I don't think I can apex on my current line with more speed. Improving the lines in those two corners alone must be worth nearly a second given the straights after both
Here is the comparison between my corner speeds and everyone else's from the Wakefield Speeds thread:
Here’s the instructors lap where he takes a much better line than me in T2 and T10 (he took 3rd through the fishhook which I think contributed significantly to his lower lap time as well as two people in the car):
As you can see I'm a bit of a data analysis nerd but it seems to help me. If anyone has any VBO data to share I'd really appreciate it.
