You seem to have an unhealthy infatuation with this clip...
This clip shows where Tewks was with his swinging "down to" (ABAF) which is why he changed his pattern..
Rich's pattern as well as Tewks pattern are/or were similar minus the forced supination.. Neither of them swing from an athletic position where the legs are supporters.....
Again Rear leg/hip as a primary driver isn't compatible with swinging "down to" due to the steep barrel path..
