I wonder how these people get so strong with such poor technique. Just a guess but maybe a part of it is not realizing it's inefficient technique. Since they don't have a good model for knowing what's off and what's on-point, their brain doesn't give them any feedback that they're off of where they're supposed to be, and they go just as hard as always. Whereas someone who knows they're off of mid-foot or whatever the case is, actually feels it, and part of their brain is telling them this lift is off. Concentration and focus there instead of just pushing through the lift at 100%, oblivious to what's going wrong. That may be totally wrong, but it's a guess.
