Sometimes.

Right ... so far in this thread, all while being in the context of the swing, you have gone from 'shift' and 'transfer' meaning the same thing, to 'shift' meaning phase-X of the swing and 'transfer' meaning phase-Y of the swing, to 'transfer' meaning phase-X of the swing and 'shift' meaning phase-Y of the swing.

I think you can see how someone new could get confused. Heck, you've been around for years and give the impression of being somewhat confused on the topic of transfer/shift.

Seems to me that understanding the phases would be the way to go. Start with FbC ... then overlap ... then explode.

Whatever floats your boat. Transfer/Shift ... Transfer then Shift ... Shift then Transfer ... FbC / Overlap / Explode.

Who cares about transfer / shift / COM / COP...learn to turn the barrel and that stuff will sort itself out. If there are issues with shift then swing it leads back to not turning the barrel.

Yep. I've been around for years...and I'm still working at improving my understanding of the swing. This thread was a step forward for me in understanding the physics a little better, and learn a more accurate way to differentiate two different types of movement (thanks, pattar and Shawn!). Maybe it helped someone else, too. That said, none of it is a replacement or revision of the mechanics that make those COM/COP movements happen.

Well then, in this thread some folks may have learned that there is a COP about the rear foot and the front foot, and that there is a higher correlation with swing speed to the COP about the front foot than the COP about the rear foot. In your opinion, what movement is happening that leads to higher swing speeds, and thus by correlation, more COP about the front foot?

Layman mechanical analogy. I think of it similar to a seesaw. Change the weight from one end to accelerate movement of the lever. I make no distinction between transfer or shift as to the weight change. The speed of the shift or transfer would relate to the speed of the acceleration of the lever. If that's the distinction others are making between shift and transfer, I understand although I don't think of it that way.

ETA, maybe [MENTION=14754]pattar[/MENTION] can fix that explanation or add something...

I'm thinking generally it confirms weight is shifting and energy is being transferred into the barrel earlier so it can be up to speed later.

I'm still trying to formulate a response to whether that Babe Ruth clip shows a shift that determines when he swings, a swing that determines when he shifts, or an example of "the swing IS the shift".

What I do know is that the clip used looks like it results in a pop-up - but I just assume if his swing was 1/4" higher, the mechanics used to get to contact would be 99.999% identical.
