If he moves the ball forward and doesn't change anything else, I'm pretty sure the ball is going foul off the 3rd base line because he'll be coming across it. I have the same early supination issue that Monte pointed out, and it's hard not to hit it left.

What causes that? And how does one avoid early lead arm supination?

If you mean the top picture, and my head relative to my right shoulder, I think it's a pretty normal range of motion that just looks weird because of the camera angle and body position. My right shoulder is doing a bit of a shrug, and I had my head tilted right. If you can cradle a phone, you too can do this nasty move!

That's a strong testimonial, given what we've seen from you recently!

Working on preventing this unfortunate move: You have to manage the ground with your feet and the club with your hands. Controlling the arms relative to the torso is what allows those two things to talk to each other. My arms have gotten way too untethered from my body pivot by separating at the wrong time, causing poor impact. I'm swinging the arms far too much, instead of letting them work up and down while the body rotates. Since I'm throwing my arms up off my chest through impact, I need to drill keeping them down and "connected" on partial swings (about P5 to P8). That means the towel drill. Lots and lots of partial swings. And hitting a few balls. I condensed about a half hour of practice into 3 minutes here, and I cut some material, but this is what the process looks like. The towel caused some stiffness in my follow through on some swings, but I made some progress on the P6 gateway, with the shaft pointing right of the target. One thing I'm missing is the release of the pelvis from the gateway (P6) to the reference point (P7.5). Much better ref point.

Gotta keep both hands on the wheel when learning to drive that Prius. 10 and 2!

For me, it's probably because I'm bending over too much and just need to let my right arm unfurl a bit more.

Sometimes I do focused movement practice indoors with a pint-sized wedge, with video. Earlier, I was trying to tease out the movements to help me get to P6 correctly. There's an interplay between the pelvis movement and arm lowering that's been missing. Pardon the emoji, I had a weird looking expression on my face.

Maybe we just have different standards of politeness then. To each their own.

@TexasTurf One basic item to look at before anything else: grip. In your FO view, there's a big clue something isn't right with your grip: You can see daylight between your right thumb and the grip, so your hold on the club has loosened by P3, meaning your right hand probably regrips at some point. I think you'll need to be more intentional with your grip in your pre-shot routine. Here, it looks like you start with the club in your right palm, then put your left hand on the club, then sort of adjust from there, with your right hand staying on the club the whole time: Most sources of instruction would have you start with your left on the club first, then add the right. I'm not an instructor, so I'll lean on some local expertise here (iacas), who has this lengthy video on grip: Since your hands are the only connection to the club, grip is crucial to setting up the actual swing for success.

You have no basis for that assumption. Would you treat someone like this if they were standing right in front of you, in-person? @TexasTurf thanks for posting your swings. Ignore unhelpful people like this dude.

Try wearing your golf shoes on the wrong feet

Awesome. This forum could use more success stories

High right shoulder is a big flaw. I was puzzling it out this morning, and it seems to come down to spine bend and tilt, and how those blend into each other. Until I can reliably figure out how to lower the right shoulder, I'm not going to hit the P6 gateway.

Tommy Fleetwood definitely has an active neck. Compare to Adam Scott: It's not a process where things fall into place automatically. It's a matter of thinking, doing, viewing, thinking, doing, viewing, and so on. I spend far more time reviewing instructional materials (all from the same source), analyzing video, and thinking about the pieces than I do actually swinging a club. The golf swing is a 4D puzzle.

Back to drilling after several days with too much going on. The video is chopped down to remove a lot of practice swings, hence the visible cuts at times. I also hit a few balls to get some sense of real contact. I'm a bit exaggerated with some of the movements here, but not enough of others. My head positioning was off before, so now I'm tilting my head to be closer to my right shoulder though impact, and getting my right shoulder lower. In trying to get to a good P7.5 and P8, but I'm still not hitting the P6 gateway correctly, and the clubhead is getting out in front of my hands. The shaft should be pointing slightly right of target coming into P6, where I often have it to the left. That's why contact is bad, coming off toward the heel. I'm putting the pieces together, and some of those pieces are rougher than others. The beauty of it is that I can sense and see on video when things aren't working properly, then work on those deficient pieces. These videos represent a very small portion of my actual practice, and I never practice without video. I'm showing my work here, even the ugly stuff, because it's an important part of the process.

I was trying it out like a decade ago and my wife (a non-golfer) dubbed it: "The Spine F***er Method"

Gotta see that swing, supes

Thanks, I'll be watching Seguto with fresh eyes now

what does "trapped" or "trappy" mean? you're always saying that

How long have you been following this practice regime? How many balls are you hitting every day? Have you seen improvement while following this routine?

I would be tempted to, because there is no universe where spending that much on a putter makes sense, if it's intended to actually be used on the course. I'd prefer not to get banned though. If you get to keep material for reference, I think this school is probably a pretty good value. If they teach you what you need to do, then you can put in the work to actually do it, that's where improvement comes from.

Do you get to take home any video, written materials, etc. that will allow you to keep revisiting and working on the same things? That would also add value.

What would Miller have needed to do to change to avoid the reverse-C finish? Is it simply allowing his head to move up and toward the targer, along for the ride with the rest of his body?

Their time is valuable and they have a lot of technology at their disposal. Seems fair
