Wildman was taught by Sonnon or one of Sonnon's certified coaches so he's moving under similar concepts as the others. We know this because Wildman says it himself in a few of his own videos.
Each individual moves in their own way as dictated by their own body, injury history, etc. - no denying that. But when you hear Wildman say cues like "crown to coccyx alignment", "grip confirmation", etc. that's straight out of Rmax/Sonnon. So next time you watch Wildman move, look for the concepts/principles underlying his movement.
Shane Heins at Onnit was an RMax coach under Sonnon back in the day. On the surface level I guess he might look a little different than Wildman in how he moves, but look more close at how he aligns his spine, how he times the shifting of his hips as the club moves side-side, etc. At a fundamental level, he moves pretty much the same way.
