Gauge calibrated??

Please bear with me. Ok, we have to gauge it anyway. But let's just say we gauge a ball at 4.3 PSI and we gauge a second ball at 4.6 PSI.

Now we drop each ball from a height of 6 six feet. The first ball bounces (for the sake of example) to a height of 4 feet six inches. The second ball bounces to a height of 4 feet 10 inches.

Don't we now know that any volleyball that bounces to a height of 4'6" when dropped from 6 feet is a legal ball? Further, don't we know that any ball that bounces anywhere between 4'6" and 4'10" is a legal ball?

What conditions could change the allowable bounce? And if there are none, why then gauge it every time?
