Bob Jewett's post 13 seems to be getting little attention and he points out an important fact. While we "call out" the balance point from the butt end, what matters is distance from the tip.
A typical 58" cue will have a balance point at very close to 19". My personal cue, sixteen ounces and sixty inches, has a balance point at 21" measured from the butt. Measured from the tip that puts the balance point just the same as the common 19" from the butt end.
The balance point doesn't matter a lot until one of two things happens. With it too far back the cue can want to float out of your bridge. Having to apply down pressure with your grip to keep a stick from floating out of your bridge is awkward. I suppose it could be gotten used to but why? Weight very forward again feels awkward. The cue also feels heavier than it really is.
Some of the old masters recommended holding the cue at it's balance point, some four to five inches behind the balance point. I forget who said what. For my personal use, I find just enough to keep the stick from feeling like it wants to float out of the bridge is fine. Never measured, I suspect three to five inches behind the balance point might be a good guess.
That extra two inches of length on my cue comes in handy when I am indulging my bad habit of stretching instead of using the mechanical bridge, no real purpose in normal play. I am 6'-2". However, I find moving my hand back on the cue to be a bad habit unless matched by moving my bridge hand back, another bad habit in my opinion.
