Neil:
I agree with Mike here. I finally had a chance to watch your two videos, and I chose this second video to do so (to me, no use in watching the first video, if you've already self-diagnosed your own video).
A couple things:
1. It looks to me like you have a case of the "grabby grabbies" -- meaning, a hook in the cue delivery due to the [possibly forced] opening/closing of the grip hand. On many of the shots, one can see your cue tip hook violently to your left (the viewer's right) after contact with the cue ball. Yes, it's after contact as far as I can tell (which is of no concern if the cue ball is already away)... but is it? Only a slo-mo video can tell. One thing's for sure; I'm not a fan of the opening/closing of the grip hand, because it's far too easy to "force" the opening/closing, especially when the shooter is under duress (e.g. playing a high-stakes/-profile match, or if camera shy). Forcing the opening (on the back stroke) and the closure (on the delivery) can and does induce yaw in the pull-back and delivery. As you know, the human hand is an asymmetric device, and opens/closes in one direction only -- fingers to palm. This unidirectional closure can pull the cue offline.
2. It looks like your stance has you "standing away from" the cue. Almost like you are angled more than 45 degrees to the cue as you hold it, and you're "leaning over" from that stance "to meet" the cue. As evidence of this, your rear end is way over by the collection of object balls by your table's left corner pocket (your left, as you stand at that end of the table), but your right arm/elbow is "out there" in space over by your table's right corner pocket, not even close to your body, even though the elbow is properly positioned over the cue. It could be my perception / camera angle, though. And, it could be, too, that I'm biased to the snooker stance, which has one more square-shouldered over the cue. (As you know, I prefer the snooker stance, because it positions you where you're delivering the cue "from your chest" -- right arm is very close to the body, and you use your body to help stabilize the arm rather than have it flap in the wind. Again, IMHO.)
3. Great PSR -- you repeat the same movements every time when chalking your cue, viewing the line of the shot, positioning your feet, shuffling your weight a bit to get comfortable, and then bending down into the shot. Great stuff.
4. You get through the cue ball quite nicely. A nice "snap" as that elbow snaps closed, and the tip descends onto the cloth perfectly. I would recommend that while in this Finish position, that you take a moment while "down there" to look, to see where your cue tip is pointed in reference to the line of the shot. You'll see the hook-to-your-left that Mike and I are talking about. (Again, I personally think that's due to the dreaded "grabby grabbies," and possibly due to the "standing away from" the cue, where you might have the inclination on the pull-back to pull the butt of the cue towards your body, injecting a bit of right-to-left correction on the delivery.)
Great video! I hope to make one myself this weekend, and post it here as well. I do this same exercise on 9-foot tables, so it will be a little different in proportions. I'll try to fit it into the weekend schedule, no guarantees.

A few comments:
1. There is no opening and closing of the bridge hand. Cue just stays cradled in my loose grip.
2. Yes, I am quite "sideways" to the shot. If you watch the first video, you will see me "squarer" to the shot. Like Mike, I am plagued with having to stroke straight. I don't get away with a terrible stroke like you see some do. Close to straight worked for years, in my older age, I want more. So, I set up a mirror (not as easy as some make it out to be, it's a pain in the arse to get one at the right height and angle to see what you want to). I saw from the first video that I had the cue to the inside of my arm. That meant that I had to co-ordinate the delivery of the stroke, instead of just letting it happen.
The position you see me in in the second video is where I had to be to get the cue under my shoulder with my arm in line with it. Looks weird, looks awkward, but isn't awkward at all to me. We are all built differently, and that is what I had to do without getting all twisted up.
3. You need a PC to be able to do this, not a phone- hit play/pause constantly, and you essentially can freeze frame the whole video. Place the edge of a paper or something along the line of the cue. Doing that, one can see exactly how and when the cue is off line.
Take shot #2 in the video. Looks like I hit it real good. However, doing what I stated above, I see that my initial line up was off a small amount. Being a straight on shot, I could see that it was, and did not stand back up. Instead, I adjusted slightly without changing my stance. Slow pull back stayed in line. However, when I added speed , being a little out of alignement, my hand did not want to go down it's correct path, but down it's natural path which was a little off. My subconscious picked it up and corrected it mid swing to hit the cb where I wanted to. Followthrough still went off path of straight. That it occured after contact is visible by the fact that the cb did indeed come straight back, meaning I hit the cb where I wanted to, just not like I wanted to.
You will see that everytime I did not draw straight back, my cue was off line a little. (who said this was an easy game??)
4. Don't know if this stance will stay permanent or not. Still a work in progress. This was shot after I finally got to where I could see my shoulder and arm in line over the cue in the mirror, then tested it out on ten shots, then filmed it. (can't see the mirror when filming, camera in way) Pleased with the improvement, but not done yet. Goal is to get a very repeatable STRAIGHT stroke. I notice that if my forearm is not straight down from my elbow, that is when I tend to go off line a little. Very touchy, will find a way to make it easier. Snooker stance is out, can't get down that low. But, very pleased with the improvement! On the right track, just a few more things to iron out and then make it habit.
5. PSR- that shuffling of my feet is getting the correct visuals for CTE/Pro1. Getting my body aligned to the visuals correctly.
Thanks to those that did comment on both videos. Never too old to learn (I'm 59) and never have said that I know it all. Far from it, just more than most.:grin-square:
