I know that CSG grades under 10x magnification currently, but how about PSA and SGC?

Have their policies changed over time?

For instance, in the case of PSA, the time that the card was graded is evident from the cert number, I've noticed that cards with older cert numbers look worse under magnification than cards in the same grade with the recent cert numbers. As such, I wouldn't be surprised if there was a change in the magnification policy for PSA over time.

For SGC, I cannot tell from the cert number when the card was actually graded (I could be wrong, but I don't know how to tell), so hard to say for sure.

Thoughts appreciated.
