In the OP's post, I counted 52 1970 Topps cards that received a 10 and I assumed that out of the cards that didn't get assigned a 10 in the submission, 3 of those cards were 1970 Topps.
As such, it would be interesting to calculate the probability that out
of 55 1970 Topps cards submitted, what is the likely-hood that that 52 would be graded PSA 10 assuming 'everything being equal'.
(Back of the envelope calculation ~ 10^-101).
Basically, you have a better chance of winning the powerball lottery 11 times in a row than receiving the grades received in the submission for the 1970 submission alone.

I was a Math major and have always enjoyed statistics and probabilities but I was never trained in the Back of the envelope technique. The calculation looks about right to me.
Nothing better then a few numbers to back up claims.
I also checked the list of 1979s and can't find Bo Derek. I believe that was the year she got her 10.
