I meet everyone halfway: I set up with low hips and the bar over the balls of my feet, but then I'll put my hands on the bar and pull it backwards until it is midfoot as I set my back and raise my hips. I stop here for a second before the lift though, so not what you would call a dynamic start, but sort of, ish??
That's the problem when anyone can watch YT, go to an Attitude Nation seminar, and immediately start "coaching." The two Soviet coaches at my gym have been marinading in the system all their lives, and it wasn't until nearly the twenty-year mark, when both were more or less done with serious lifting, before either before even thought to try coaching. That said, I did ask them about the role of heavy back squats and pulls, and the consensus was that there's a place for them, but only in the earliest block of a training cycle, or if technique is way ahead of strength; otherwise, a lifter's limited supply of recovery points is better spent practicing the actual movements. Has nothing to do with "interfering with the movement pattern" though because that'd be retarded.
