Use e.g. a V1 software. Use the Spline feature. Use the same time intervals and mark hands position each time. You will see (no matter what golfer - used even Ben Hogan driver FO vid) that the hands are initially accelerating, then slowing a bit before coming into the impact zone.
I know that it's an imprecise tool but it rather confirms what Dante discovered, not your revelations, Nm.
I am very objective. Try it yourself before you start negate what I tried.

Cheers

I believe Nesbit's test data not your V1 software spline feature.

Drawing on stills or footage never made any sense to me anyway .... parallax etc. But you're free to believe what every you want to believe.

There there are undoubtly some golfers who's hands slow down some (Nesbit measured some golfers whose hands did) but very very few golfers hands slow to the extent of Dante's stroboscope model.

Its not worth my time discussing this hand speed issue anymore (as you know it was beat to death on that other forum).... the DATA speaks for itself and the DATA SAYS GOLFERS HANDS DO NOT NECESSARILY SLOW DOWN BEFORE IMPACT. (see figure 4 in linked pdf) Read Nesbit's comments on matter. Either you believe it or you don't end of story.

It's not the question of my belief. I always tried to be objective and love the objective truth. Thus, I take seriously Mr.Nesbit's researches as well as e.g. Mr.Dante's ones. However, there is no final evidence for one or the other theory - otherwise, the discussion on this or the other forum would not have been necessary.
You can laugh at my V1 trial - and I understand it because I myself stated that it's a imprecise tool - but, it shows what it shows. This is what I wanted to say, nothing more.

Cheers

To some I'm sure many questions remain unresolved. I'm not sure specifically what those questions are though.

COAM has absolutely nothing to do with either the release in particular of the golf swing in general. Furhermore not all golfers hands slow dow before impact. Nesbits data proves it. These are statements of FACT not opinion. In otherwords that IS the truth but then some people cannot handle the truth, particulary if it does not fit with their preconceptions It doesn't matter to me what you or anyone else choose believe. Have a good weekend.

OK, give me a link to a FO vid of a golfer that accelerates hands linear velocity - I'll convert it and compare to my YouTube findings. I am sure you know, at least, names of golfers whose hands are not slowing down. Have a great weekend too.

Cheers

NM can you put your noodle on a new tangent and examine the science coam principle in relation to the center of mass..ie pivot.

CG or C of Rotation? Not necessarily the same...

OK I get....

noodle = brain
tangent = thought process

After that you lose me.

I'm science based. I go by numbers (data). I refer you to figure 7 or linked pdf (above) there is you angular velocity for 4 different golfers. Its increasing (at slightly varying rates) for all golfers. Its not constant and there for the concept of COAM does not apply.

Help me try to understand where you're coming from. What is it about rejecting the COAM myth that troubles you? For instance is it because you've come to believe COAM is responsible for the release? Just asking.

no nmgolfer im interested in delayed hip action..for e.g move the center of mass to the left earlier while the shoulders/arms/hands are still loading . So they move forward on an angle..bit of a lull..and then boom

OK... I'm with you now... I'll attempt an answer before I leave...

Basically I agree with Bio's mentor (Welch), i.e. the brains in that operation. Wether walking or golfing we create "motion" by shifting our CG thereby creating a temporary imbalance. In the golf swing we "fall" (and catch ourselves). Where I differ with Welch's concept its the notion that that its the shear force reaction at the feet that is what's most important. That concerns motion in the horizontal plane but it neglects the larger motion in the vertical (yes I know horz. and vertical are not the "correct" terms here). Bottomline is all golfers are (falling) in some combination of horz AND vert.

Just a suggestion... If yYou want to improve your golf swing, take the spikes off your shoes and go practice hitting off loose dirt (using a tee) where your feet will slip if you apply too much shear force. It will teach you to "fall" in the vertical plane. IMOP that's key.. that's where the "power" is at.

Take a look at young Mike Austin. http://www.mikeaustingolf.com/video/early_lessons.wmv He's falling around a posted left leg. Centripetal acceleration keeps him rotating about his posted left leg the same way it keeps the moon rotating about earth. He's falling in the vertical (not horizontal) plane. Even still, angular momentum is changing ... its not being conserved.

So the normal force distribution/shifting between the two feet is key. Mike called his the compound pivot or weight shifting pivot. http://www.mikeaustingolf.com/video/at_the_top.wmv


I leave you with this: COAM and Kinetic Chain Momentum transfer is BS. Hand path and learning to fall correctly are key and always Swing easy hit hard.
