You may have something as far as stance is concerned and maybe explains the break shot where the best 9 ball breakers rise up and finish with a tremendous elbow drop. But if you look at the Snooker players, the classical stance is with the chin on the cue and it seems that the best players today have a drop. Very small but consistantly there.The only thing you need is a pat on the back for having observant eyes and an open mind.
I filmed myself the other day, and I noticed that I have a slight elbow drop on most shots. At the time, that was a little disconcerting.
Then at the pool room last night I was watching Rodney Morris practice, and I was specifically looking for the elbow drop. And guess what? It was there.
Now one thing I noticed that Rodney and I have in common is that we are both a little more upright in our stances than a lot of other players. It then occured to me that the higher you are in your stance, the more vertical your upper arm becomes, and the less swing range you have from the elbow down. That could lead to some forward movement of the upper arm (elbow drop) in order to get a full stroke through the ball. For further evidence of this, look at how low Allison Fisher gets over the cue. That allows her more swing range from the elbow down; and she does get a full stroke through the ball with no elbow drop.
Now, I'm beginning to think that stance height, forearm length, and bridge length all play a major role in whether the elbow drops, or it doesn't.
What do you think? Could I be onto something here?

A very subtle difference but still there.
