In autocross shortest distance almost always trumps carrying momentum, even in low powered cars, get tight on all the important cones (some cones aren't worth getting tight to, that comes with time).

If you've had a coach or someone you've connected with that you know is fast and experienced, have them drive your car, even for one run, it can be mind blowing realizing where you're giving up a ton of time. Also going for ride alongs can teach you this as well, but in my experience riding along in your own car after you think you've maxed it out is a valuable lesson. Maybe you're closer to the potential than I can tell from the video in which case only data logging will reveal the differences that are a few hundredths in every spot that add up to a second or more.
