To the original post, this is a tricky question because most of us, don't have Denny as our PC. We have someone Denny taught to be a pitching coach. So each 'Tincher' is going to see and teach things slightly differently.
As an example, about a year ago our PC incorporated a double back swing (it was from Denny - much like you would doing a standing broad jump). The other 'local' tincher never incorporated it. Or at least she did not for existing students. This past winter, my DD's coach stopped my dd's double back swing and went "Of of the Glove".
I have not purchased any of the Pauly videos but I've watched all the free ones. I've spoken to Denny a couple of times but not indepth. I believe that they are both driving to darn near the same exact GPS coordinates. But the key words, drills, and progressions they use are probably different.
BI has been discussed here. RP has a few videos on it. My dd's PC does not use the term brush at all. But she has talked about shoulders back, pull the elbow down, and engaging the lats. You can't do those things and not get brush.
