if you miscue all the time you are reaching to far.
if you never miscue your not reaching far enough.
Patrick Johnson said:I think the threshhold question is whether snapping the wrist can add significantly to stroke speed. Is it possible given the arm and wrist mechanics?
The forearm is a 12-inch hinged arm accelerated over a distance of 12 inches using a large muscle. The wrist is a 3-inch hinged arm accelerated over a distance of 3 inches using a smaller muscle. Because of the wrist arm's shorter length, the wrist muscle can fully flex more quickly than the bicep, but its short length limits its added effectiveness.
The wrist's motion isn't "amplified" in a pool stroke like it is in a baseball or golf swing because it lacks the added length of the bat or club, so its contribution to the stroke is limited to the speed it can add over its own short stroke length. I can't prove anything, but I think its effectiveness is usually way overestimated.
I'm betting Sayginer's stroke speed would not be diminished dramatically with a locked wrist. By that I mean not by as much as, say, 15 percent (1/7).

I'd say about 5-10% in practice if you are working on extreme spin. Most players never get even half way to miscue territory. The first thing you have to learn for this is how to chalk and how to repair miscues.okinawa77 said:So, how many miscues are just right?
The wrist is a lever on a lever so the effect is magnified.
If Sayginer uses some form of loose wrist to achive the acceleration he gets on the CB, there must be something to it.
My guess is that the happy medium for effective draw would be (actual contact) somewhere between 3 & 4 on the Rempe ball.
Patrick Johnson said:What is this "lever" you speak of? In baseball and golf the wrist "leverages" the extended length of the bat or the club, but it has no similar extension to work with in pool - it's simply the hand itself adding its unleveraged movement to the arm's movement. I think the added stroke speed can be demonstrated by hitting a ball by moving only the wrist - not a dramatic increase.
That's the "if" we're discussing. The fact that his wrist is loose isn't proof that he "achieves the acceleration" that way.

WesleyW said:I'm practicing with some maximum english. Sometimes I got some miscueing. When drawing the CB, I would shovel it instead. So, I'm wondering how much english can you apply on a cueball.
Beneath I've add a picture, can you say where you can hit without miscueing. Will the 5-line be the maximum, or can you hit even more at the edge of the CB?
I usually try to hit the place between the 5-line and the red-line, but miscue often. Hitting the 5-line is just right to me. But shall I practice to aim more at the edge?

Colin Colenso said:The wrist does act as a lever. Or is that a fulcrum about the hand as a lever, though it is only a few inches long. That said, small levers can develop significant forces. Take the calves in jumping as an example.
So flicking or snapping the wrist can lead to significant increases in cue speed.
Of course, the CB knows nothing about any rate of acceleration at tip impact, only the mass, velocity, direction, position.
So the wrist snap, a result of a relaxed wrist perhaps, is more or less a tool to develop cue velocity in a controlled way. i.e. Without lunging or straining the body.
