I watched some D-plane stuff last night but I still didn't understand how its supposed to help me and how I get the correct D-plane..maybe I'm too dense to pick it up from the videos I watched.

My philosophy on golf "We're not doing rocket science, here."

Just the realization that a "correctly" hit iron is actually traveling in-to-out at impact (before the bottom of the swing arc is reached and a divot is taken). Conversely, a correctly hit driver is actually traveling out-to-in at impact, since you are making contact after the bottom of the swing arc.

Some people have had success with their drivers by setting up with a little bit of a closed stance.  The idea is that this will alter the swingpath a little bit to counteract the out-to-in movement of the clubhead. It seems to help me, anyway.

Some folks also try to set up to their irons with a little bit of an open stance so that, at impact (so the d-plane theory goes), the clubhead will  be square to the target rather than traveling outward.

Hogan's altering of his stance for each club may have been an early realization of what the d-plane was.  No one knows for sure. But he was an astute observer of his swing, so it wouldn't surprise me.

just to avoid confusion - just because you are hitting down on an iron does not mean the club is swinging in to out in relation to the target, only in relation to the swing direction.

A swing direction/plane of 3 degrees left and 5 degrees down can produce a straight path through impact with most irons. If your swing direction was 10 degrees left, the only way you could make that go in to out is with an overly steep 20 degree downward angle of attack, or more. This would never be a good thing.

So it is still possible to hit down on a ball and have a left swingpath. Angle of attack is only an influence. Swing direction is a bigger influence (it's 1:1 with a driver).

Oh yeah Harmonious welcome to the dark side!! To me understanding the D Plane and the Ball Flight laws should be the first things that are taught to any golfer when first start to play because they are simply that important to understand.  Once you understand D Plane you can truly understand how to get yourself in position to execute shot shapes.  And then after the ball flight laws are truly understood then you will never ask yourself why a shot flew the way it did.

I might surprise Harmonious a bit with this but I think all the talk of the D-Plane is over-rated and over-stated and over-done.

It's great to know but honestly it takes a few seconds. If hit the ball down more (because you move the ball back in your stance, move your head forward in the downswing, whatever) you'll send the path a little more "out" than you otherwise would, and vice versa.

That's it, as far as playing golf is concerned. That's about all you really need to know.

Relative to the baseline or swing direction, yes. But you can also line that up to the left, hit down on the iron, and have the true path of the club being to the left of the target. Or vice versa with the driver, of course (but H knows this).

Bingo. That's the vice versa of my above bit.

I agree. Hogan played a fade but the ball moved like a yard or two - it wasn't a big sweeping fade. Most pros move the ball only a little.

      I have an update… I don't have much of a response, because the fact that they would ADD the numbers for the lead and trail shoulder together… I mean, wow. I was giving them too much credit. Nobody would think to assume they were doing THAT. That's beyond comical. One of the biomechanists I talked to put it this way: "So if I squatted down and went from 180 to 90 deg knee angle, then I would say 180 deg range of motion because I have two knees?" I'd type more (maybe), but honestly, I'm laughing a bit too hard. 🤣 Update: Mini Manavian blocked me on Instagram, so I cannot see his post showing Bryson with about 50° of range of motion (with a driver) from P4 to P7, and 75° only if you go out to the mid-follow-through. What a terrible loss for me. 😉

      Thanks, interesting to read. The swing is definitely very timing dependent. I hit it consistently I guess but consistently bad.

      Struggling With Volatility

      By Ty_Webb · Posted

      I've shot 91-74 on the same day before. Couple of years ago played a two round tournament on Bethpage Black. I shot 72 in the first round and 90 in the second. First round I played very well. Second round I played okay, but had about 5 shots that hit the lips of bunkers and bounced down into them. A couple of those wound up in footprints - I was unamused - and I failed to get them out. Anyway - lots of bunkers and my bunker play isn't great and then add a couple of footprints and me getting pretty tired and it added up to a lot.  Only you can really tell though what's causing the variance. It might be that your swing is very timing dependent and when it's timed well you play well and when it's not then it goes all over the place. In that case, some lessons and working on your swing could be the key. If it's more that you tend to feel like you hit it fairly consistently, but you have days where the shots come off and days where they don't, then that's more likely a course management issue. If that's what you need to work on, then you could read Lowest Score Wins and build a plan of attack based on that.  Rest assured though that a pretty big range from high to low is fairly common. Even PGA Tour players often have 18-20 shot spreads from best to worst rounds in a season. It's a common affliction among golfers.
