Okay. I'll bite. What's the difference between center of balance vs COG? How it spins in a centrifuge?IMHO this is a major step-forward in chassis design-concept, if not execution.
They finally did the math on how to aligh centre of gravity with centre of balance...

The more technical term is centre of pressure.
One of the characteristics of level flight is the CoG=CoP, so having a mathematically balanced system in a rifle = level flight under recoil.
In a sense you could say the CoP is the "centre of the thing your rifle is balancing on", whereas the CoG is the natural point on your rifle wants to balance on.

How sure are we that were not overcomplicating this and trying to use terms that don't apply? Aren't we really just talking about an object that balances on another object? Is the balance point different than the center of _____ during recoil? Or are we just trying to achieve max independent stability so we can free recoil a 23lb rifle? If we really cared about engineering for recoil reduction we'd probably want a majority of weight forward or to the rear of a balance point to counteract recoil. Not, coincidentally the same point that also allows the rifle to balance on a prop without any influence from the shooter.The more technical term is centre of pressure.

TBH, I think a lot more people engage in some sort of free recoil than they would publicly admit and I think an indication of that is how much weight we want to put on guns and how much we're searching for the perfect balance point on a prop. It is true that if a rifle sits on a bag, on a prop without you touching it...that it doesn't move. It's perfectly still. So if you can manipulate that situation as a mechanical natural point of aim so the the reticle is centered on the target in a wind hold, any wobble is coming from the shooter influence. In more awkward positions you can back off the cheek and shoulder pressure to reduce your imparted wobble. At the cost of recoil management. In more conventional and easier positions you can put more into the gun and yield better recoil management. But the majority of shooters that are seeking to leverage weight and balance are using balance to reduce their required input into the gun and weight to manage a large portion of the recoil. So I don't think we're as interested in finding some high level "center of centrifugal -flight during recoil" concept. I think we're just trying to get a gun to balance on a prop.

You're overcomplicating this respone.
Its all very basic, and you can get to the same place without any math very easilly.
the point about "the math" is it works before you build the rifle. ie, you can look at a part list and determine if the rifle is balanced or not before you assemble the rifle, and likewise you can determine the "balanced weight" of the complete rifle once you set the balance point (ie the CoP).
And since you know the parts-list you know the $ cost.
The context of this discussion is chassis design.
A good chassis/stock design for PRS should reach ideal balance with a minimum of added fuss.
I'm overcomplicating? Lol.
I have to hand it to you. That was a good bait and switch.
The answer is simple. the balance point of the rifle needs to sit in the middle of the thing it's balance on.I'm overcomplicating? Lol.

there's nothing hard about that at all.
the only real difficulty is predicting where this point is before you build/buy it.
