[bioengine]

That's one of my weaknesses.



I appreciate you efforts. It's very interesting and helpful. I see more and more of BioMechanics on the Web. You're much better than others I've read and I'm finding merit to much of what you say.

Daryl,
The problem with biomechanics is anyone can by a biomechanics software and start researching. Although there are two factors to consider is the quality of the software they use. You can't compare a 38,000 dollar system to a 250,000 dollars system the cheaper version isn't anywhere as accurate.
It's like polhemus systems is no where near as accurate as a Vicon system.

Also you should question the researchers background and what it is they researching in the golf swing and how they are researching.
There are a few companies who have no qualifications in biomechanics or human movement patterns also using cheap systems.

They work of buzz words and basic knowledge, also they add points of view and opinion and measure science, they don't to stick to the laws of motion and physics.
This makes it very difficult to educate consumers with the truth have these guys out there muddying the water and confusing people.

I hope one day in the PGA there are two type of coaches geometry and physics coaches, each understands the others field so they inter grade and work together for the better of the game.
