This is something I have started to work on post impact as well. I may have had a lightbulb working on superslotting over the weekend. I was working a very exaggerated half swing…really sending the arms hard left with the pivot. I then found it very difficult to get the club up to the finish. There was pressure being exerted from the right arm and shoulder to keep the club down. So I have to really work to get it up to the finish. I have the feeling of pressure on the club the entire post impact DS doing this. I am just now exploring it. Here is a 3 wood I shot this morning. The pressure down extends all the way to the right leg and foot, and you can see here the right heel never comes up. Not sure if that is a good thing for my back in the long term…will probably have to let the pressure go at some point. I shot a 5 iron caddyview as well that I will upload later.
Recently I had a Déjà vu…
On the end of the vid is a video of one of my first teachers some 15 years ago
(look at the post impact work)…
He tried to teach me his version of hitting - but I didn´t get it then…

I’m wondering what do we do with a picture of Ben Hogan like the one below. The picture is from Power Golf. Is he losing his shaft flex? Was retaining shaft flex something Hogan was concerned with yet? Was hogan ever concerned with retaining shaft flex through impact? if the answer to the final question is yes, what is the available evidence OTHER than trying to observe intentions in his swing.
By the way, there is a whole host of pics over on the sandtrap.com forum from Power Golf. Here is the link to the thread http://thesandtrap.com/t/38758/power-golf-by-ben-hogan#post_826457
Rolling shutter effect. Camera lens distortion of the shaft.
If you turned the camera upside down and took the same shot, the shaft would flex the other way. Even many new cameras do this.
Some cameras are accurate in this regard while others are not. My best camera was a Sony CCDV101 with 10K shutter frame that could stop a hummingbird’s wings.
The Power Golf book will continue to falsely confuse golfers for decades to come regarding shaft flex. I wish this never happened.
Think this instead…
Nice.
I have never seen that picture before. Thanks for the clarification.
Are there any clues to look for when trying to discern whether a picture is being falsely represented via the “rolling shutter” effect or is the viewer at the mercy of the technology?
I guess my question is will a camera in the same or similar position ever distort the shaft in the other direction? i.e. showing held shaft flex when it is not present.

Interestingly in Power Golf, Mr. Hogan wrote that at P3 - it is the time to uncock the wrists…

I have the Power Golf book with the pictures as well and have to reread it, where it was quoted…
Chris
If one really wants the proof about the camera distortion here… all you have to do is look at the above photo
from the backswing. It would be impossible for the shaft to be flexing in this direction while taking the club back.
It would clearly need to show the shaft flexing in a trailing way… not a leading way.
Well someone’s catching on out there…

baby steps back to good golf…
From where is this NRG?
Here are some data from my hip acceleration profile…
This is the data from Charly Hofman…
My swing was with a 9 Iron and Charly Hofmann a full mid Iron.
This app gives a score for your acceleration and deceleration before impact - I have maybe the worst score, because
my peak acceleration begins after impact.
My hipmotion accelerates slow and gradually and then peaks after impact and keep accelerating -
compared to the kinematic sequence who spins the hips fast and early and then stalls to have a
high deceleration… Of course Charly´s hips are more open at impact - nothing left to accelerate.
Somehow interesting …
Chris
P.S. lol, the app says I should stall my hips pre impact to have a better MTRX score…
Chris,
I think it’s from a calender that was released by the benhogancollection.com in 2007.
Thank you very much NRG…
Just want to show my crosshanded swings - no way to SS it crosshanded, but good feeling thru impact…

The shaft stays a long time inline with the left arm…
Chris
Very impressive Chris. Another instructor a long time ago did that so I tried one range session and could never even find the ball!
Thank you for the compliment, I have the feeling it is not very different from my normal swing pattern!

If you stop the video directly after impact it looks like I play crosshanded…
I don´t play tennis, but if I hit a ball only lefthanded it looks like I play a one handed backhand…

IMO it looks quite wired and not like a golf swing…
Anyway, good for coordination skills…
Chris
Hello everyone, I am new to this forum and a poor golfer compared to everyone here, lowest off 5 now creeping up at 49 years of age I am fundamentally trying to change my swing and working really hard to get more lag and stop my ott move, more from the inside etc. Really struggling with maintaining spine angle. watched the whole of the fantastic moe Norman private lesson and am now confused about what I should be striving for. The hogan lag swing seems totally at odds with the Norman straight arm no hands involved single arc swing. Any clarification would be much appreciated. Also Thanks for all the info in shutter problems, I have been worried about my shaft flex due to this picture, it’s obviously a problem with early release. Sorry I am going to sound really dumb to all the experts here.
Here is how you tell if your camera is accurate.
Take a swing as you did… and view the shaft flex…
Then flip the camera upside down at take another vid. Likely all the flexing will be opposite.
Unless they are the same from both camera set ups… you are dealing with camera rolling shutter distortion.
Moe was similar to Hogan in many ways… both had excellent forearm rotation through transition. Moe in his prime flattened the shaft into the downswing as most all the greats did. Moe’s left arm and shaft inline from DTL view is the optimal way I believe to use a swingers release. Check out the Moe thread here and Greg Lavern has a lot of good info on how Moe did things. He spent a ton of time with Moe and his book is excellent. Greg swings more like Moe than anyone else I have seen.
Welcome to the site.
I did a video with my Iphone 4 near impact:
Here with my Casio FH 20:
Both vids are 30fps 720p quality… different result thru rolling shutter distortion…
With the Iphone4 camera my DG x100 shaft looks like a noodle… with the casio normal.
High end cameras have faster readout speeds and therefore milder rolling shutter artifacts than low end cameras.
Chris
If you ever question your camera,
Video your swing, then simply turn it upside down and shoot your swing again.
If the camera is spot on accurate, you will get the same look to the shaft either way.
In most cases, the shaft will bow the opposite direction when flipped.
Do you find it easier to hold the shaft flex on a practice swing as opposed to a real swing?
Makes no difference if a ball is there or not. The ball is just in the way of the swing.
