What's your cue's Pivot Point?

Is it true that the tests performed by Predator and Platinum were both done without any reference to a pivot point?

So how long did you find your pivot point to be?

btw: After testing, I can say that Mike's test, where he aims at a ball 20 inches away, results in a pivot point of almost twice as long as my test. The reason is that the throw from the spin has quite an effect.

If you separate the CB and OB by 40 inches, the pivot point comes in nearer to the pivot point that I measure. at 60 inches they are basically the same.

If the CB and OB are only 10" apart, the pivot point on most cues would be near to the length of the cue. This is because of the SIT.

Though at 10" you can make it work with a 20" bridge using a large offset and a lot of power as squirt is increased and throw is decreased at speed.

The pivot point method I suggested is simply to indicate the cue's basic squirt characteristic.

btw: I found the pivot point will vary at speed. From 14" for slow shots to 7" with a lot of power and extreme english. The slow shot includes some swerve, but the difference is not entirely due to swerve. 10" is a pretty consistant result for medium to firm shots for my cue.

from 10 to 15 inch, depending on the shot.

I believe these are simply squirt tests.
However, I expect squirt test measurements could be accurately converted to a corresponding pivot point.

As a guess, a low squirt of 10mm might translate to a 14" pivot point for medium-firm shooting, and a 20mm squirt might translate to an 8" pivot point for the same speed and tip-offset.
