Who remembers the old setup Bob did with the machine designed to test deflection?
It was a joke.

FYI to those interested, detailed information for why cue extensions do not change CB deflection characteristics of a shaft or cue, see:Neither. Only the mass of the first several inches at the tip affects squirt.Say you have a 58 inch 19 oz cue and you want to add 8 inches of overall length.
Which setup would result in more cuing deflection for this cue?
1. An 8 inch, 2.5 oz shaft extension
2. An 8 inch, 2.5 oz butt extension
FYI to those interested, detailed information for why cue extensions do not change CB deflection characteristics of a shaft or cue, see:
shaft endmass and stiffness effects
what causes squirt?
Now, if you add weight with an extension and use the same stroke for a given shot, there will be more CB speed and less swerve (but the same amount of squirt), so the net CB deflection will be more. For more info, see:
CB deflection speed effects

Nope.Wouldn't your bridge length have an effect?
No, you're looking for the pivot point where your cue's angle in one direction = the squirt angle in the other direction (compensating for squirt only, not for swerve).When you are finding the pivot point of a cue, you are looking for the point where swerve cancels the squirt at a given speed, is it not?
... not on the amount of squirt the shaft produces. See:Wouldn't your bridge length have an effect?
Bridge length does not affect squirt; but if you are aiming in a way that relies on a certain bridge length (e.g., BHE and/or FHE) and you change bridge length, then you are correct, the aim will be wrong. But it will also be wrong if you change anything else (speed, shot distance, cue elevation, conditions, etc.).If you use an extension, you are usually increasing your bridge lenght, because you need the extra reach for a particular shot.
When you are finding the pivot point of a cue, you are looking for the point where swerve cancels the squirt at a given speed, is it not? So using that for a basis, bridge length should affect squirt?
Why was everything else bullshit? The OP's question looked to be fairly clearly answered and explained.I was going to post an answer but after reading all the bullshit everybody else posted I forgot what I was going to say.
Wouldn't this mean people who use an open bridge should get more miscues? Wouldn't that mean if they don't get more miscues they're not hitting as far from centerball (i.e., getting less spin)?

.Here is the correct answer which I normally reserve for my pay website which all the top players subscribe to...
... not on the amount of squirt the shaft produces. See:
squirt bridge length effects

...I know Earl’s cue was very heavy when he went to the long one.

I don't think bridge length or using a normal mechanical bridge should affect squirt.

All the homework you need is at the links in my posts above.Now I'm more confused then ever. This is in your description of pivot point..
"Effective pivots lengths. (compensating for the combined effects of squirt and swerve) for a wide range of shafts (for a given shot speed and distance) can be found in the shaft comparison table."
But now you are saying bridge length doesn't effect squirt? I have more homework to do.

The "effective" pivot length and the "natural" pivot length are different things.Now I'm more confused then ever. This is in your description of pivot point..

Of course pivoting at a different length doesn't work if that's your method of adjusting your aim to compensate for squirt (backhand english).You don’t think that altering the pivot point will feel like a different amount of deflection when aiming?
