I wonder if this deeper notching is part of the launch problem... if during a match with deeply notched strings, if you take an easier swing or a defensive swing without using a lot of topspin... maybe the strings are "locked" in the notch, giving a trampoline effect rather than the impact energy being put into moving the strings along out of place so they snap back? Newly strung un-notched strings slide easily, heavily notched strings do not slide without sufficient topspin applied?
you could be onto something here ??????
