You suck! Take up golf!
Oh wait, you wanted 'constructive' criticism.
I don't have my track map in front of me, but after the esses/autocross section, there are two three right handers in a row. You want to hit, miss, hit those apexes. You hit, hit, hit. The middle turn you can be 1/2 a car width off the apex and you'll be able to carry more speed into a late apex on the last right hander (I throttle steered around that one and the subsequent left hander). You'll only need to use 1/2 to 2/3 of the track out which will set you up for a very late apex on the left hander prior to the last corner before the 2200 ft long straight (the most important turn on the track).
There are bits here and there, but that was the area where you gave up the largest amount of time.
That data overlay would have been really useful 20+ years ago when I started doing this track stuff. Very cool!
It was fun to see all of the above at the track.
