(In your post #6 seen above here, the only part originally posted by me is underlined: The remainder you changed & wrote in yourself. Though anyone just reading only post #6 & not reading my original post would assume I'd written all of it, in that order.
If you quote me I'd prefer you then didn't change the content.)
This is what I did write, if attention is paid to the parts now in bold, particularly to the parts in bold, italic & underlined, should be reasonably plain that this is a 'guide' to a 'goldilocks model" written in conjunction with the vid (this being a model which has an 'area' in which things would be in better to fall within as it would cut then down the need for compensations in timing & movements in the swing motion more of these there are the difficult it becomes to consistently find center)
"Once in your posture with the Club your arms should hang vertically from your shoulders, then just move the Clubhead behind the ball, same is true whatever the club, the total distance away will vary with the length of the club. But the distance the hands are away from the body should be always pretty much the same, as the arms hang from the shouldersthe upper arms (triceps) should lightly be in contact with your chest (pecs), so use the distance the butt end of the handle is away from your body (so better to use that as your guide) Staying in your golf posture arms hanging vertically if you take your right hand off but keep everything else the same if you then continue to hold the club in the left hand in it's position on the handle with a vertical arm hang you should then be able to fit approximately the right fist plus half a thumb should fit between butt end of the handle, in this position, & your body." This suggests that everyone,
however they swing​, ​should stand the same distance from the ball. If you look at Jiminez his arms clearly don't " hang vertically" from his shoulders. Kuchar's hands are immediately below his chin and Furyk stands much closer. In general, it seems to me the more upright you swing the closer to the ball you need to stand. I don't think you can give this advice without knowing the swing.
The OP looking for some guidance because there are some difficulties in him feeling he is in the area both in posture & address that would be better to start from, to be able then to find a centered contact with a reasonably square face angle that more consistently enables better results than the shot direction issues currently being experienced.
This not really something that either Fuyrk, Jimenez or Kuchar currently has an issue with, as they, as extremely gifted Tour Pro's find impact pretty good, though none would really be used as a 'goldilocks model' for a handicap player experiencing difficulty.
If you look closely as both Miguels & Matt's address position with driver, you'll see that in both of them, their upper arms are in contact with their upper chest (pecs) & in both of them their arms also hang on a vertical plane (not a more held out diagonal plane reaching away from their chests)
If you also look at the gap between butt end of club & their thighs, you can see that despite there very different physicality's (Kuchar tall, long legs shortish body, Jimenez shorter legs body closer in proportion but barrel chested) this space is not so different, about a right fist plus thumb & a bit (the 'bit' goes back to my original post of saying 'should be always pretty much the same")
If Jim had, as a child, been unable with his more off the norm address/posture unable to find a consistently good impact position by being not able to make the compensations needed in time & space his address position/posture dictated, so not resulting in a good shot outcome. You can bet your last dollar that his PGA father would have then started to change a bunch of things to enable him to be able to do so in a better way. But he saw the contact that his son could get on a consistent basis & decided to leave well alone.
Chicken & egg. Thing everyone does first with is a club is hold it, find a posture, stand a certain distance to the side of the ball find aim & address aim alignments etc - so far the club hasn't moved - & these positions will all vary to some degree giving everyones different stature. But everyone has to do this first, how everyone then is in these 'stactics' has then a huge influence on how a club moves in any swing motion.
I have seen both the DTL & Face On videos of a number of the OP's different swings with driver.
