I don't think anyone is asking for 10 decimal places of tolerance on the diameter.... However a single decimal place or 2 would certainly be welcome.

Honestly I would take one or the other if it helps consistency in an event and event to event. Right now, we don't have either besides a general 'look' and 'feel'.

The actual result can be seem using chemistry.

Lets say we have a 25'' Sportlogo ball, and a 24'' AndyMark ball, I know their the same ball
R1=12.5in
R2=12in
V1=(4/3)pi(r^3)
V1=8181.23in^3
V2=7238.23in^3

Ideal Gas Law, PV=nrT
Assume (nrT) is constant between two balls.
We have have (P1)(V1)=(P2)(V2)
From above (P1)(8181.23)=(P2)(7238)
Notice the two pressures cannot be the same.
Lets say we inflate one ball to P1=7.5PSI, NCAA Basketball recommendation pressure
Now we see that P2= 8.477PSI

What does our result show? Well the Smaller diameter ball is at a greater pressure. Meaning that it is firmer.
If you try to instead control the pressure you'll see that you get stuck with a different ball diameter.
