Neat vid's you have been doing Shug. Since these comments can get side tracked into a lot of different things that would not help you at your current stage, I will keep my comment brief. (assuming the reason you are posting is that you are looking for help to improve)
It appears on the vid of watching you the pilot, I would venture to say your handle is too big for your hand. You are cinched up on the upper portion of the handle, and there is large space below your little finger and the bottom inside of the handle. Some might think that this is fine as long as you always pick up the handle the same way, but really, it is not... because you will always pick it up a little different, and when your hands are oily or sweaty it will move around, and, you are inducing more handle loading on the down control with the extra overhang to the bottom by doing this. It's subtle, but since you are at the learning stage, and are gaining muscle memory now, it would be best to head things like this off before that becomes your norm and nothing else feels right.
I don't think it's going to terribly helpful to comment on aspects of your learning the pattern yet until you fix that, like say, for instance, I also noticed your inside loops were walking one way, and your outside the other way, and get bogged down in wind placement discussions while you are fighting that handle still.
So... if you still haven't tuned out yet and decided that I'm a total idiot, what I would do is for expedience sake, get some thick racketball handle tape and wrap the handle ends to narrow it up until your hand is centered, and see how it goes, then if you like the improvement, eventually get a smaller more comfortable handle.
Hope that helps and makes sense,
