"A stiff cue deflects more than a whipper [sic] Moochie." How do you mean? Shaft deflection or cueball squirt?

Another deflection thread. Does whip *increase* squirt?

Both apply
So stiff = more deflection? I think that's what most people on this thread are arguing against.

No they are the same.
Same.
What's confusing is that people use the term "deflection" both to talk about the deflection of the shaft (i.e. it flexing) and deflection of the cue ball (i.e. cue ball squirting). So when someone just says "deflection" it's hard to understand if they're talking shaft, or ball.

Usually the more English applied, the more squirt, the masse curve effect. Low draw deflect jakced up very little, center ball level cue same, jack up high deflects like a mother, its a masse shot. Hit same shot with a perfect level cue and perfect level follow through level to the bed, very little. So its all about jack up and hitting center ball folks.
From the results of various experiments mentioned or linked to in this thread, it seems that:
Reducing tip mass reduces deflection.
and
Anything that reduces the elasticity of the collision between the cue tip and the cue ball increases deflection. These things can include a softer tip, increased tip radius or a more flexible shaft.
So it stands to reason that stiffening a shaft will decrease deflection only until a point where adding material to the shaft does not significantly reduce shaft deflection. Past that point, adding material doesn't significantly decrease flexibility enough to counter the extra squirt caused by the extra mass.
For example:
All else being equal, I would hypothesize that a 6 mm shaft would deflect more than a 12mm shaft, because the shaft's flexibility contributes significantly to the deflection. I would also expect an 18mm shaft to deflect more than a 12mm shaft, because the extra shaft material contributes more to increasing weight than it contributes to decreasing shaft flexibility.
Disclaimer: This is not a tested scientific theory. It is only a hypothesis to reconcile the seemingly contradictory results of different experiments. If tested, the hypothesis could prove to be incorrect.
