Here's a video of my 2nd run. I lifted a bit for a fraction of a second in 1st gear at the launch when I started spinning. In retrospect, if I could have a re-do, I'd probably just keep it planted and see what happens.
I think that for my first time power shifting I did pretty well. I never hit the rev limiter on a "no lift shift".
