Stroke straightness and Digicue blue - 01-13-2018, 05:52 PM

Recently became much more serious about my game after a string of mistakes that cost me matches I should have never lost.

Purchased a Digicue blue to help analyze my stroke and any faults I consistently have. One of which appears as "straightness" in the app. It's the one thing that I cannot figure out how to fix. I have my ups and downs, however this is more like bad and worse.

I've attached 2 screenshots. One of my stats on a recent shot tonight while doing for Lowry stroke drill. The second is the in app description of what it measures.

Can someone better explain it to me or provide an explanation of how to fix It? Now that I'm aware of the issue I've tried different things I know of and nothing really seems to change that one particular issue.

I've reached out to Scott Lee to see when he will be nearby. Waiting on a response.

If you use a pendulum stroke it will always have a bad score for straightness. Try dropping your elbow.

That straightness measure will only get a high score if the stick moves in a perfectly straight line, INCLUDING up and down.

I was one of the beta testers. I ended up customizing the settings, and removing the straightness component entirely. I kept the tip steer instead.

I understand that much but still feel like I should be better than 2.0 consistently

Experiment with your elbow in order to get a perfect piston stroke, and a high score. If you donít like how that feels, then delete the straightness from the tracker

I also had to delete the finish tracker on mine. It wants you to stay still for an eternity.

Ymmv Good luck.

I have the same problem. Canít fix it. I tried laying the cue flat on the table and hitting the cue ball like that. Straightness is fine then. I think you really have to keep that cue level. Itís annoying and frustrating.

Straightness measures how close your forward stroke is to a perfect piston stroke. You will score low if the cue moves in any direction other than straight along the stroke line. If there is a significant amount of vertical movement in your forward stroke, most commonly caused by a pendulum-type stroke, you will score low.

I don't want you to be annoyed and frustrated. It is OK to not have a high score in some areas, as long as you are aware of why that is. If you want to improve in those areas, you can. If you don't, then its OK to ignore it or turn it off. Use the values from the device as a characterization for your cue action rather than than a pass/fail judgement.

Note: Since the DigiCue BLUE measures straightness and tip steer only right before impact, it could be argued that a perfect pendulum stroke is traveling perfectly straight (with zero vertical force applied) at this time... and thus is possible to score high on straightness with a pendulum stroke. To do this you need to make sure your upward swing occurs after impact with a good follow through (not punchy).

What does 'straight' have to do with 'level'? They are unrelated. Sounds to me like a flaw in the program.

Fran,

They are unrelated, and there is not any flaw in the program. The DigiCue BLUE does not measure any parameter in relation to elevation angle, or what you are referring to as level. The device will perform the same regardless of cue elevation (unless very large elevations are used, >45 degrees).

The DigiCue BLUE does measure parameters in relation to the stroke line (but not the shot line).

Straightness measures the deviation from the three-dimensional vector path of the stroke line.

Regards.

Digicue Blue and the Pure Pendulum Stroke - 01-15-2018, 03:55 AM

The blue has been valuable to me in identifying stroke error. I also have a pendulum stroke. I changed to a piston stroke and progressed through the Advanced level. But it bothered me that I had to leave the pendulum behind.

Well it turns out that there seems to be one move that allows the pendulum stroke to move through the advanced. On my stroke there is a raising of the wrist on my follow through which drives the tip down towards the cloth. This raising occurs before ball contact (slightly) and continues into my follow through. This ruins the statistics.

So, I worked on this arching of the wrist so that my stroke was more parallel with the cloth before contact and after contact.

For me this is a better stroke. And the Digicue Blue is happy !

Then I guess I must have misunderstood an earlier comment by you (see below). It seemed to me that you were saying that cue elevation did have an impact on straightness score:

Your comment: "Note: Since the DigiCue BLUE measures straightness and tip steer only right before impact, it could be argued that a perfect pendulum stroke is traveling perfectly straight (with zero vertical force applied) at this time... and thus is possible to score high on straightness with a pendulum stroke. To do this you need to make sure your upward swing occurs after impact with a good follow through (not punchy)."

What is an upward swing? I know of only backswing and foreswing.

A pendulum stroke moves along a vertical plane. I am calling an upward swing the end of the foreswing in which the butt of the cue has both vertical and forward velocity.
