After some digging, I’m pretty sure I know where the 1/10000 claim for the SMPY 3rd cohoty comes from - the original creator of the study tested 396 gifted students (who were roughly in the 98th percentile of their class), 7 of which scored above a 700 on the SATM.
I am pretty sure he is above 140. He seems substantially smarter than me and probably of a relative of mine who tested at 150 (professionally administered tests in a research setting)
