EErrrrmmmm sorry to be a party pooper but ....

at 0:51 ... that isn't a parallelogram
at 1:59 ... the critical angles A,B,and C, are irrelevant as the force acting along the line of the arrow is a resultant vector of the net resolution of the sum of the forces acting on it.
at 5:19 .... where is the lever arm that creates the rotational moment?
at 6:43 ... the open stance brings the dominant plane of motion of the major tri-planar joints orthogonal to the face of the target where muscle force is at a minimum.

... just sayin'

#1 Technically correct. Was simplified for people or he misspoke?

#2 Again correct. But as the "best" way to shoot would be if we could be TOTALLY "Inside" the bow, in between the riser and the string, thereby reducing stray vectors to zero. I'm sure that that is part of why Warbow shooters seek to shoot "inside the bow" as much as is practically possible. But there are practical limits to just how much "inside" you can be.

#3 The lever arm is the upper arm being pulled on by back tension? Look at the diagram and animation and visualize the upper arm as being like the connecting rod in a standard internal combustion gasoline engine, and the forearm is the piston. The shoulder joint is the crankshaft "throw" and we are manually cranking the engine around. View the "piston" as being near "Bottom Dead Center." Drawing the bow is like the "Intake Stroke" of a 4 stroke piston engine. I may be wrong, but that is how I see it.

#4 I wasn't clear on this one. Are your shoulder joints tri-planar joints? If so then I get your point. Get the shoulders at a right angle to the target. I myself shoot a closed stance, which comes from having started many years ago with a compound set for a draw length too long for me. Subsequent attempts later in life to shoot more open stance have not been good. But that's just me.


Now we can blather on about about this at great length. Probably have a good time and I may even accidentally learn stuff. :)

So all that aside, I do want to point out that I have found that shooting The Wedge is superior to the so called "Form Clock" that has been being pushed on another Traditional Archery site for many years. The Form Clock leaves the shooter stuck in the position that Archery Winchester referred to as a parallelogram. It promotes weak back tension, and extra, unwanted force vectors.

Rednef In hind sight, I think I deserve a slap on the wrist for being so pedantic and hyper critical. I respect your opinion and knowledge way too much to continue with my childish outburst :sorry:

I like the "wedge" alignment but have trouble putting it into practice in anything but light clothing. Because of that it's not a good solution for me since all of my shooting is practice for fall hunting season.

I end up with the same yearly dilemma, what works for me in heavy clothing in October and November is not the best way to shoot under "normal" conditions. I think I shoot a little better the closer I get to the described wedge and it's disappointing to not be able to commit to it.

Rednef .. the shoulder is a tri planar joint. It can flex and extend (sagittal plane, divides the body between left and right) ABduct and ADduct (Coronal plane, divides the body between front and back) and internally and externally rotate (transverse plane, divides the body between up and down).
What I do like about the video is ... it demonstrates how, as you bring the bow arm alignment in line with the plane of the Pectoral girdle, it converts the pulling mechanism from a four bar linkage to a three bar linkage ... that's something archers need to appreciate

Here is my take on the subject:

"Minimal points of complex articulation . . ."

keep it streamlined. A straight line between the

drawing hand and the bow hand is ideal.

Unfortunately not possible, the Wedge shape is

an acceptable compromise.

And one I strive for (that and the dropped shoulder of the bow arm).
