Not too shabby at all!
The only thing I can tell is it seems like he is "over bending" just a hair in the nose/neck in your turns, and it seems to slow him down in the turn too. His last step in the turn seems "stuck" when he should be blasting out of there.
What if you gave him the opportunity to turn the barrel on his own, and leave him alone with your hands? What would he do?
Also, you held him up going to the first barrel. He really seems to be working the turns good though. What happens if you send him in at Mach 20?
Will he miss it or will he turn it?
