Bronco Billy,
Still very curious about all your theories, measurements or any evidence you might have with regard to the heavy hit, which you seem to keep jealously for yourself. A forum is an ideal place to share and discuss any interesting idea or concept you might have concocted.
Don't hide your light under a bushel and shrink your posts to just a simple point. That is not much fun. Why not add anymore the usual endings such as - Have a Great Day With Your New Found Knowledge.... or , Thanks for Spreading the Gosiple and Have a Great Day...
Shaft Flex
With regard to measuring shaft flex, more data is available from Max Out Golf and their product ShaftMax,
Custom Golf Clubs, Putter Fitting, Golf Evaluation
which measures the deflection put on a golf shaft during the entire swing. The results are then presented in a graph. I had this done when being fitted for a new driver, and the information was very helpful. I would imagine that it would also be helpful from the instruction end as well.

"Brian,
The shafts for irons don't bend very much. There appears to be indeed a small forward bend just prior to impact and quite a substantial backward one, just past impact, due to friction force caused by contact with the mat. Nice to have these stills. The rather large backward bend in the shaft past impact surprises me a bit but then again one can't argue with facts. "
I believe you will find that the backward deflection of the shaft is caused by the club impacting the mat (ground), not the golf ball.

What do you think is implied in my post by friction force caused by contact with the mat ?

If you watch a very high speed video you will see that the iron shaft actually bends quite a bit. When you watch the actual video of a 10,000 frame per sec , the shaft is all over the place. With graphite it moves so much it is suprising that we can make contact.
Brian how many frames per sec is that camera?

Maybe this will help
On the T.V. show "Time Warp" they film all kinds of things with their high speed cameras. One episode they were shooting a baseball at a Louisville slugger held in a vice at the grip, to see at what point you had to hit the bat to break it. When the ball hit the bat to their surprise it flexed as if it were rubber.

Let me clarify.
First of all, I'll take some super high speed video with a Driver off of a high tee.
Second, I KNOW THE GROUND CAUSES A LOT OF THE REBEND, that's why a lot of forward lean makes for and even HEAVIER FEELING "hit."

rcw,
Just another nail in the coffin of the heavy hit theory. There are so many nails now that the wood starts splitting and the coffin getting so heavy requiring additional people to carry it to its final resting place. I feel that Bronco Billy should be invited to give a helping hand.

Brian,
Do your experimenting with care, cause if you come up with noticeable bending for the shaft during impact hitting with a driver not touching the ground, some explaining has to be done.
Cochran et al. in their rather convincing experiments used a free moving hinge in the shaft close to the clubhead and even so found virtually no deflection of the shaft during impact.
Okay, please discuss... not prove
And your example refers to visual stimuli. I have read some internet articles that a "trained" touch circuit (like swinging a golf club) doesn't need to travel to the brain.
So my best guess is that someone who is naturally quick and has trained on specific physical actions would have reaction times more like 5,000/10,000 milliseconds. (I can't prove it though)
That's still a little more than ten times the impact interval, but a very imaginable relationship.

Please, when someone discusses and critiques specifically values and magnitudes the first thing one should expect from this person is to be precise with his arguments, doing so.And your example refers to visual stimuli.

5,000/10,000 milliseconds means 5 to 10 seconds. I am afraid that you live on another planet with reaction times so extremely slow that golf is completely impossible.
trying to be cordial
Mandrin,
Your post had a pretty serious error on the reaction time. I was trying to be nice while I pointed it out, that's all.
The rest of the readers let it by without questioning it. You might be good at math but I have picked up some inconsistencies and weaknesses in your posts.
As for your "rest in peace" insult....I was just trying to be nice, show some humility because you are always claiming how rude people on this board are. It appears you are the rude condescending one. And I might add your social skills are at odds with your math ability.
But never fear, I have idea(s) to help you.

Nihil Sub Sole Novum
DP3,
Dear friend, your post had a very serious and gross error on the reaction time, my post however quite obviously did not. I was trying to be nice while I pointed it out, that's all. Claiming reaction times to be from 5 to 10 seconds is indeed quite of the scale. Try to do better next time when you feel an irresistible urge for nit picking and please keep to the essentials. If you feel that being gently corrected for gross errors is an insult to your ego, than so be it. Interestingly there is however some quaint familiar smell to your posts, this characteristic fast transition from sweet to sour, we will see before long if my intuition is on the right track. In the mean time brush up a bit on mathematics, especially since you want to pick holes in my mathematics. The best of luck in all of your endeavours.
