The problem here is that there really are many little optimizations that could be applied to "pick up, put down" and some do work. Injury avoidance and recovery in particular are easy to overlook.

Of course the magnitude of the effect from most optimizations is small, so it's pretty easy for con artists to claim some secret or new breakthrough.

At the very highest levels people want every edge they can get, but it's silly for most of us who aren't devoted to competition to go down these rabbit holes. Pick up / put down / don't get hurt goes quite a long way.
