Pretty interesting video, I think I am going to get some impact tape to see where I am hitting the ball.
I need a poor man's trackman.

That's what I've been saying with how you can hit a straight pull with a path that is not to the left. Hit it off the heel and that could straighten it out even if your path is square or inside-to-out.

I hit one fairway yesterday (scored great) due to hitting it off the toe all day long (left city). Went to the range tonight and was surprised how much my hand path had to change to get my face to hit the ball near the center. I used a lot of impact tape to confirm my hypothesis. Trackman III looks awesome!
Iacas -
Did you get the Trackman III?

Wow... I never would have thought the ball flight would be changed THAT much due to impact location.
No wonder why I can hit giant push draws with my driver despite not getting the feeling that I really nutted one... and then every once-n-awhile hit a huge push slice that felt great.
Now I'm 100% lost, lol.

Yup, what it also says to me not only do professionals have very consistent path numbers, and the face angle may vary a little more, they are incredible at hitting it in the same place on the club or the ball would be going all over the place.

It's been in Trackman's newsletter. If you hit your driver with a square path and face and miss by 1/2", you're going to fly off-line by 35 yards. I believe one can pretty much feel a 1/2" miss. But less than a 1/2" is harder to feel if not impossible. IIRC, Ralph Perez had a video from the 2011 PGA Show on the latest model of Trackman and they showed a strike by Sadlowski that was like John Graham's strike. It should have been a push-cut, but it was actually a nice push-draw...Sadlowski hit it off the toe. Check it out...it's on page 3 of the July '09 Trackman newsletter www.trackman.dk/download/newsletter/newsletter5.pdf3JACK

Well you combine this and Joe Mayo's recent video that talks about divots not being useful then watching your ball flight one can only make "general" statements about what is happening.

Very cool video by John Graham. Thanks for sharing!! What's very interesting to me about this are a couple of things: 1) Swing direction correction feedback to neutralize the clubpath with regard to AoA, Swing Plane, Swing Direction could be best suited for a center strike. 2) Neutralizing the club path for an off center hit could have two different adjustment methods based on club type (driver and irons) due to the bulge & roll of the face, club COG, and horizontal gear effect imparted. John Graham presented a driver situation, so it would be cool to see a similar video with an iron. - Note a Positive AoA of +2.6 & negative spin axis (or weak draw) was demonstrated. The rule of thumb in adjusting for swing direction for a positive AoA with driver is a 1-to-1 ratio between AoA and Swing direction. Applying the rule of thumb for adjustment in swing direction would be +2.6 (this cancels out the effect when the clubhead travels upward, it is also travelling from out to in relative to the target line). Not correcting this for a center of club hit could lead to a left to right ballflight.
- The toe hit, or first shot, has a draw flight, so aligning the swing direction be more right can have the unintended consequence of making this weak draw into a stronger one and further away and left of target. The solution would be a swing direction change more left, or approx. -3.6 degrees to cancel out the draw action of a toe hit with an +2.5 upward angle of attack.
An untrained person could end up making adjustments that make the shot worse (eg I'm trying to follow the advice intended for a center hit, but completely unaware of how off centre my shots are). Or worse, introduce new swing habits based off poor striking (eg - you get used to hitting it off center, that when you do hit it on the screws - the present face and path situation turns the driver into an anti-fairway finder. Perhaps this might be a situation you've faced before and it wasnt golf instruction pro feedback or lessons helped to straighten it out. Regards, Todd

Any idea why I have to feel like I "push" the clubhead in the downswing away from meand towards the ball the ball to stop toe shots with woods?

Perhaps natural tendency to stay extended so you don't lose that half inch or so in a toe hit. As an alternative, you could stand closer to the ball to avoid 'feeling' this way.

I had to do the exact same thing the last time I was at the range. Simply standing closer didn't help me. I found the toe seemingly with a Jim Furyk setup. It's as if I was sensing the sweetspot in the toe as opposed to the the sweetspot. So I just had to trust that I was going to hit it in the center and not the heel when I pushed the clubhead out away from me.

Anyone understand why he says that the direction of the divot doesn't reflect clubpath?

I think he's saying that the divot tells next to nothing about ball flight because you can't tell what the face angle is doing. I think he's saying it gives a rough idea of the path, but that's obvious not all to the ball flight.

FS tells I'm coming mainly 2deg in to the ball but my divots are all the time to the left as they should be. But the really interesting case is how those devices find that 2 degrees out or in or even smaller differences.
