Digicue Blue question about parameter "Finish"

I bought a digicue blue one year ago; I have good results in all parameters, except the finish, it's the most challenging parameter for me; I know that I have a little elbow drop, maybe for it, I have a bad result?
If I drop my elbow after contact with the cue ball??

It's most difficult to get better results with hard shots than with soft shots.

I appreciate any advice on getting better results in this parameter.

Thank you
 
My unprofessional answer is that elbow drop is an unnecessary complication in your stroke, but it may or may not be an actual problem (especially if only after contact). I'd try to keep my elbow still.

For a more complete answer from a more worthy source, you should also ask your question in the Ask The Instructor forum:

I have a digicue also. I think it's reporting that your follow through is too short in duration or that you are moving up (to stand) too quickly after contact.

Mine biggest problem is straightnes.
 
If your shooting arm (just that one) is long enough, then an elbow only stroke might cover it. Otherwise, you have more issues not dropping the elbow including injury from repeated torquing of that one joint.

The most important thing is what's in front of you. Make sure all adjustments you make to your backhand have desirable results up front.

regarding the comment above bolded by you straightline
1) are you saying that dropping the elbow is better than not dropping the elbow ?
2) can you explain how no elbow drop "torques" the elbow"?

If your arm isn't long enough to pendulum the whole range of pool, you _will_ have issues trying to keep the arm from dropping. The elbow can only fold so far before the joint is in peril. Torquing is what happens when the elbow runs out of travel while the player it's attached to insists on not dropping the elbow.

By biggest problem is staying still and only moving the elbow hinge. I think I have the rest of the fundamentals down but I am working on them all.

Couple things seem to work there. Stand off to the side of the stick and shoot side eyed (unless you have a deformed neck like Sigel) or stand snooker style and get down and square with the stick. The less you get down the more free linkage you have to stabilize. I've done both ways and both ways work. I settled on the 'down on the stick' snooker stance and elbow drop.

I cant imagine where someones FOREARM cant pendulum enough for the whole range of pool.
could you give some specific exmples?
torques definition when i looked it up i got this
"a twisting force that tends to cause rotation"
the elbow is a hinge joint it does not TWIST in normal use.
when the elbow "runs out of travel" it does not torque or twist it stops when the forearm meets the upper arm

Being a hinge the elbow is subject to angular rotational force. As far as running out of travel, short guys can't power draw without dropping through contact and/or releasing. Even taller guys will sensibly drop the elbow to keep things linear - on any stroke. My take is if you pay too much attention to looking pro, you may just be letting more dog into your game.
 
Can you explain /gice examples how the elbow is subject to angular forces?
hunter lumbardo power draws fine and he is short and has a very minimal elbow drop

Hunter is a developed pro. But as you said, elbow drop. Something has to give.

The bicep force is angular to the axis of rotation - the elbow.
 
I’m sure you read it, but for others, in the digicue app - go to History. Click on any particular entry in the shot history and then click on the parameter you want to know about. Here, finish. There’s a short (.5 second) buffer after contact, so just stay still for a little while. I can shoot with/without elbow drop and finish with a “high” score. You just need to stay down longer. One tip: don’t move your head AT ALL until the object ball goes in the hole. If your head is still - everything should also be still.

the bicep pulls linearly not angular
the elbow moves linearly not angular
hunter has a pendulum stroke
his minimal drop refutes your statement not support it
sorry for this off topic banter guys
you can ignore us
pm me straightline if you have a rebuttal

I think some of the DigiCue parameters are a bit to tight for most humans to score well on, and some don't matter much if you score "low" on them. When I was playing around with one I had several players that all were worse players than me try it out. Many of them scored higher than me in the app in several categories, but would not beat me in a match. I did notice that players with bad mechanics that are bad cause the thing to scream in pain with the low scores they get LOL And a second thing I noticed about them, soon after trying it out, they quit using it. The did not like to see the negative feedback show up telling them what they were doing was bad. Needless to say those players have not stuck with the game and stopped showing up to play.

It's a really good training tool I think, but you need to get rid of any ego when using it as you are learning it since lower level players will be getting low scores in many of the categories.

The bicep merely contracts. The force is linear. It applies torque to the joint. It rotates the forearm. Torque.

If you use an IC engine as an example, sure the motor is a twisting machine. The torque is defined separately from HP as the rate at which the twisting force increases or decreases. Once again, the twisting is generic to the type of generator.
If I'm not mistaken, lbs feet used to be calibrated to a horse dragging or lifting via pulley, a dead weight. That's a linear force.

Oh, and Hunter's (I don't know him) drop _is still a drop_. Also he is usually observed on fresh, well maintained equipment. Power draw under those conditions is more a function of touch and restraint than raw cue speed. I think the drop may be to maintain cue linearity or to minimize mashing the shaft into the table.

Sub, power break for power draw. Now what?
 
the elbow when acting as a hinge joint has no torque since there is no rotation
any "torque or rotation " of the elbow joint comes from movement of the ulna and radial bones which produces torque of the forearm not the elbow the humerus bone does not pronate or supinate
 
Mike Massey must be 6'5".

How do you suppose you get the pendulum analogy without rotation?

I'm at least a foot shorter than Massey. With no elbow drop I have about 10" of useful stroke.
