Why won't you admit there's more than one correct method?
OK, there's more than one correct method. Golly am I happy that's off my chest.
We teach that very same principle to all our students. While the warm-ups, timing & rhythm may change from player to player, our final strokes are all just about the same. I agree with Wolven here.
That's why I asked you for your definition. The stroke is your final movement forward. Hopefully it's repeatable, dependable and accurate.
