Leading shoulder - lifting, sliding or rotating?

[Coder]

Hi all, long time visitor - first time poster...

Would you agree that the lead arm and club shaft are in more of a straight line at impact than they are at address? If so, then the straightening-out of that line means that the lead shoulder must be a few inches further from the ball at impact than it was at address. How much of that distance comes from lifting the shoulder towards the sky, versus sliding it towards the target, versus rotating it open?

I suspect I'm doing too much lifting and not enough rotating.

I think that in most situations you'll find that it's a little more "around" the arc it traces: it'll be a little bit further forward (toward the target), a little bit further up, and a little bit further left (away from the ball).

With the driver, in particular, the "forward" part will tend to be a bit minimized.

Red is initial (if the camera moves, the red dot on the ball gives an idea of the magnitude). Green is at impact.

Thanks for the photo analysis @iacas - good to know that a rising shoulder isn't necessarily wrong. For me I think it tends to go along with early extension but maybe that's a discussion for a member swing thread someday...
