@5263: I believe the term "yank" is appropriate if one also accepts that the pull across and up is rather abrupt. In other words: yank = abrupt up/across pull. I believe it is appropriate to call this motion abrupt since it introduces a sudden racquet head acceleration at that point. IMO, there's no need to confuse this with the concept of pulling back on the racquet handle. I think I had also called it abrupt in some earlier post, but decided not to press on for fear of getting into a needless and lengthy argument - ha ha! Surely, even abrupt motions will look smooth in slow motion video - it only looks abrupt if one sees it in real time. However, to misquote an old aphorism, "one man's smooth is another man's abrupt", so IMO it's not a point to dwell on!
