Yeah, who would think that kind drill is any good? It is also the kind of 1:1 application drill you will find in BJJ, Muay Thai, Boxing, and MMA and they are clearly wasting their time doing that. BJJ, Muay Thai, Boxing, and MMA also circle/move laterally, but clearly that must be a waste of time also.
Somehow I think Phil's approach is light years ahead of yours.
