I understand your concept and I think it is actually a pretty valuable one (though I would imagine all good high stakes players already understand it, intuitively.)

The only thing I have to add is that I'm not sure the term "stack efficiency" is the best name for this concept.

Your efficiency decreases as your stack increases which makes you less likely to resteal which makes it better for your opponent to steal against you. There are too many conceptually disparate motions for this terminology to catch on.

I was discussing this concept with another 2+2er just the other night and mentioned how I thought you could use a stack-size disparity as a lever on the bubble. Maybe "leverage" fits this idea a little better than "efficiency."

I don't know, it's your idea so call it whatever you want. But from a marketing standpoint you may be able come up with a better slogan.

Half of the reason why the PVS gets so much notoriety is because the name is cool.

Maybe you can just call stack efficiency "V"
