I've gone back and looked. It looks pretty apparent there are at least more than 300, although how many more than that I don't know because I have zero idea on the dates of the differing data. There could be more than 400-500 unique hands in that data- but again I cannot tell with certainty.

Even including the data for players with 400-500 hands I cannot imagine the picture as we see it changing. What you may find is more players in the greater outliers- but that's about it.
I'll look later to see if I can tell which shots are unique to come up with a number for hands played- but I'm pretty sure the talked about number was north of 400.
