I ref volleyball and the psi range is 4.3 -4.6. I can tell by feel if it is 4.3 or 4.5.

LOL. The ball can vary more than over a psi just to temperature at playing conditions alone!
At that low of a PSI, you should be able to tell. Once the ball gets hard enough, it becomes much more difficult to tell. They’re discussing 11 vs 13. At 10 it’s pretty rigid. Even a basketball is only 8, and it’s larger and round. More rigid, is...more rigid.
Assuming the ball would survive, do you really think you could tell between an 11 and a 13 PSI volleyball by squeezing it with one hand? They’d both be rocks...and crushing isn’t exactly a normal volleyball motion.
Exactly. The very idea that a pro with over a decade experience can’t immediately notice a 20-30% pressure differential is not remotely believable.
