Rich points out that it helps raise the nose or narrows into release, too. Something I can totally appreciate and better comprehend now, when comparing all the variations on spin.
Forgot to add: In an ideal rise release, how much (if any) brush is involved?
I took the clip of Parkers rise, slowed it down with the Technique app, it looks to be all the way to the middle of her hand.
How did you do that? I've been trying to figure that out for some time but cannot seem to get it.
