I think you're trying to do too much with your arms for a ramp that size. There's not enough time to throw your arms straight over your head and then get them back into a good position for the turn. You end up turning with your arms over your head which is probably making it more difficult than it should be, and doesn't really allow you to work on dipping your head.
I get the gist of what you're going for, but I don't think it's the right ramp for it.
Would be curious to see you try a backside run on this ramp where you keep your arms below your head and just focus on the top turn once you've built up some speed. You're already pumping down the ramp which should give you plenty of speed, no need for big sweeping arm movements going up the other side.

Jason Daliessio Nice, I'm in NJ.
I'll give my thoughts about it after the sessions and hopefully have some video to post.
I'm mainly hoping to work on improving my front side carving turns/cutbacks.
