The reasons why videos are important is because we could literally spend 15 years throwing theories out with no progress (and boy have we lol!) but a series of, or even to start with, just one video showing 10 shots in a row, unedited, goes a long way to demonstrating the effectiveness of the theories involved.

I think it should be restated that many styles can work. All you need are certain principles. A means to maintain consistency, the ability to fine tune control and a few other things are the only prerequisites for someone to be accurate.

So no one is necessarily discounting the possibilities of what you are saying but like I said, showing that you can achieve that with what you are saying by posting a short video lets people know there is something worth looking into.

All of us only have a limited amount of time, so to show someone there time is well spent studying or thinking about what you are saying, videos are by far the best way to do that. I promise it would take less time to post a video than it would be to post multiple posts on a thread.

That being said, I love your theories. I think you may be on to something with the lateral oscillations and some other things you mentioned. So don’t take this the wrong way.

A slowmotion clip for study behavior of the sling. The release cord is gripped side by side of retention cord and upon release is in front of the retention cord, but the pouch angle automatically assumes the correct position for a rifled spin due to minimal oscillation, without requiring cord seperation. This is why I recommend minimal oscillation theory

Many of these things become self evident to slingers,  like that a wide grip is less secure in general than a narrow grip. It's also very easy to test and perfectly logical to understand the reasoning behind it. 
I have read about these things since my entry on this site and I've never seen anyone disagree with it or make a case against it.
It's simple, when the cords are seperated in the hand, the sling is already partially opened, the wider the seperation, the greater the opening, the greater movements on the projectile in the pouch that can cause slippages. On the contrary, with a pinch grip the sling is fully closed. The projectile doesn't move around in the pouch. It literally takes 5 seconds for a slinger to test.
Place the loop on the pinkie for the widest seperation, and the projectile is least secure. We can naturally assume
that as the seperation gets less the projectile gets seated better, and try it out and see it in front of our eyes. Isn't that obvious?

I talk about two types of oscillation. One that happens when either the cord is too floppy for the projectile, or the projectile too heavy for the sling, and one type of oscillation that happens when a wide grip is utilized, which worsens as the grip gets wider.
The first type results in cord twist, which leads to erratic pouch angles, and thus erratic releases. The second type of oscillation comes as a result of trying to solve the former type, by widening the grip. This oscillation happens up and down, and causes the projectile to experience a rolling movement just slightly so in the pouch. I am not sure if this has an effect on release
accuracy, but it can lead to preponed release. A solution for this is stiffening up the pouch or making the pouch more cupped, or swapping to a style with less rotations, but all these are not really good solutions and bring their own downsides in my opinion. The better way to solve the first type of oscillation instead of widening the grip is to get the appropiate type of cord stiffness for the projectile or the appropiate weight and size of stone for your sling, and what is appropiate? When it doesn't oscilliate / twist back in forth  with a narrow grip too much. What is too much? That is personal. For me I don't like it more than 20 degrees.

Sarosh explains very well why we can't keep making our slings thinner and floppier and expect the same accuracy

Size, density, weight, all plays a part. The shape of the projectile as well. A sphere by its very nature produces the least oscillations, while the more elongated and longer the projectiel gets the more oscillations are introduced.
Higher density also produces less oscillations than a lower density projectile of the same weight. It all has to do with the way the mass is distributed and centered between the sling cords.  The more of it is in the middle and not outside the pouch the better.  It's why I like the fat clay glande a lot. One that is almost a sphere, but with points.

I've already explained it, and I don't feel like repeating myself over and over, because I can't explain it differently than what I already have. And if you don't understand it, than I can't help it. Maybe one day I will find better wording, but currently I am at a loss for words for further explanation, because I feel like I've already said all I could to explain it.

So I think the main issue I have is if a person says something cant be done or cant be done well and then even one other person does it, it sort of destroys the whole theory.

Its like saying only one throwing style is capable of high accuracy. Well, thats a problem because now every single person who is halfway decent that uses a different style is gunning for you. Once they accomplish what "cant be done" every single thing that has been said in conjuction with that disproven statement becomes suspect and people naturally tend to dismiss it.

This is why its far better to put your theory out there, build on it but dont ever act like its all figured out unless you have a ton of scientific evidence to back it up.

And even then in science with real researchers and people with all sorts of letters behind their name you still see their theories get absolutely demolished on a regular basis.

I can say for me personally Ive had some pretty darn good accuracy with paracord and wide grip apache slings. And I can probably count the amount of unexpected releases while using decent ammo on one hand. And thats out of 10s of thousands of shots. So that right there is a big problem.
