Just how accurate/exact are "pressure signs?"

What standards or specs are there for them?

I've shot hundreds of 7.62 NATO proof loads (65,000 CUP) and none of their fired cases looked any different than the same case, powder charge and primer used in standard loads (50,000 CUP). Standard load used a 147 gr bullet, proof load used a 172 gr bullet.
