The statistician/data scientist in me would love to run experiments like this. But my financial advisor/wife claims it's an unwise investment. Maybe someone will set up a 'GoFundMe' and I can donate to the cause lol

Let's say we could buy 100 random PSA 10s from 4SC fairly spanning their price range, with other people's money. What's your guess as to the distribution of what would come back if we resubmitted them all raw? I would guess something like 20 10s, 50 9s, 10 AUTH, and the rest 8s and 7s. That might be high on the 10s.

It would depend quite a bit on the type of cards we selected.

If they were ultra-modern shiny cards, I suspect it might be something like:
60% 10s
30% 9s
7% 8s
1% 7s or lower
2% Authentic/rejected

If 80s junk wax with older certs
10% 10s
30% 9s
20% 8s
10% 7s or lower
30% Authentic/rejected

If vintage with older certs:
<1% 10s
15% 9s
10% 8s or lower
75% Authentic/rejected
