I seem to be getting quite a few spurious "chirps" apparently caused by cue movements away from a shot. I know the manual says to hold the cue at more than 45* angle to avoid spurious beeps, but I thought the chirp could only be triggered by an actual shot.
Any thoughts on minimizing or eliminating these spurious chirps? It will be disappointing if not, because one of the things I was hoping for was to use the device as a kind of "odometer" of how many times I had shot, in a given period. This would allow me to track my average (I play 3C) and see if it is improving over time.

We ship USPS Priority, usually 2 days anywhere in the U.S.
The unit itself weighs about 1.3 oz.

We've had some other users mention this as well. The sensitivity is currently set real high to avoid missing soft shots. Spurious shots can be deleted pretty easily with the software, but if it misses recording a shot there's nothing to be done. Abrupt cue movements can cause QMD to record a spurious shot.
That said, we're working on a user adjustable sensitivity setting to let you set it to what works best for you. It'll of course be a free software update.

This information is extremely useful and I like the suggestion above about being able to export your data to a cvs file so you can import it into another spreadsheet for analysis.
I haven't used the new version yet but will soon to see how it is.
Interpreting the metrics for your shot 12.....
All the metrics measurements are variances in degrees from the position of the cue when you address the ball (the set) right before the backstroke begins.
0.00 to 0.70 is the lateral (sideways) range of the cue movement during the entire shot from start of the backstroke through contact with the cue ball. The 0.00 to 0.70 range means the tip of the cue ranged from pointing 0.00 degrees left to 0.70 degrees right during your stroke.
-0.44 to 0.34 is the vertical (up/down) range. The tip of the cue ranged from 0.44 degrees high to 0.34 degrees low during your stroke.
-5.06 to 14.79 is the roll (twist) range. During the shot the cue rolled in a range of 5.06 degrees right (clockwise) to 14.79 degrees left (counter clockwise).
The 0.54 right, 0.44 high and 5.06 right are the lateral, vertical and roll position of the cue at the moment of impact with the cue ball.
For this shot the lateral range is pretty tight, the overall range of 0.70 degrees is only about 3/4 of a tip and this is pretty good. The vertical range indicates this was a piston type stroke (or a bad pendulum stroke with elbow/shoulder dropping). For a pendulum stroke you would generally see the tip pointing mostly low and barely going high if at all. There was quite a bit of roll, 14.79 degrees clockwise, in this shot.
The numbers in red are metrics that fell outside the customizable metric goals that are set for each metric. The metric goals can be set to highlight for you the problem areas you may want to focus on. Once you've established your goals, the less red the better your practice session is going.

thank you for the analysis
i do have a pendulum stroke which from video analysis in the past shows my elbow drop occurs after contact
i cant wait to have more time to use the QMD
i like the fact that there are real measurements to follow and tract
but also the visuals of the stroke from the different veiws especially the back view to me helped me see how my cue goes off line
i might have my house pro use it
i would curious to see his results
With the Windows version of QMD you can copy/paste the chart on the Metrics screen right into Excel.
