No doubt the better your eye/hand coordination the more likely you are to Ding!.
No doubt remaining relaxed and having a level of concentration that keeps your mind empty of thoughts also helps a great deal.
The method I developed is based on knowing I am left eye dominant.
I pause at the top of the back swing to give my computer's CPU time to settle down to a low % usage level. In fact I use Window's Task Manager CPU Performance % display to watch the CPU's performance level. (I have the display minimized to my task bar at the lower right of my screen)
Once the CPU settles down I start the down swing.
I then move my head to look left at the already moving meter. I consciously favor my left (dominant) eye and follow the meter by moving my head to the right along with the meter and click the mouse at the appropriate distance before the Ding!.
Not counting putts, I would guess my Ding! % at about 60%. I most often click the mouse a bit to early when I move my head corectly but still miss the Ding!, and most often miss the Ding! late when I don't move my head or don't move it enough.
When putting I often compensate for the break by purposely missing the Ding! early or late.
For putting I also use a Putter Pal like display (VGG Caddy) so I can use just a short portion of the meter (not often more than 20%). When I do want to Ding! a putt I likely nail the Ding! 80% of the time, and am very close to the Ding! the remaining 20%.
