Thanks for the detailed answers.
Your guess makes totally sense.
Enenthough the angled motion does not escape in both directions it does not slow you down. That’s a pretty good explanation to me.
For stringhopping I am not totally sure. I remember when you teased the last Andy wood interview you asked us to find out what’s going on in a short clip and added a warning that he is using stringhopping when he played slow. I agree that for some people the problems caused by stringhopping are small or maybe even not there. But I still think in the very beginning it’s what most if not all people do.
Anyway the main question is basically answered by your guess. Wrist extension works against repetition when not used correctly. All other methods lose accuracy or cause unwanted notes but the motion/timing is kept.
My tortured brain is happy again
Thanks @Troy
