If anyone is interested,
this might help some of the ranking discussions. I believe JBG is also using it for the wiki.
If anyone has any (similar) data for earlier rounds and wants to send it to me to add, I'll add it. I'm not sure if any other information would be useful.
This is on the beta site for a reason! It's not final etc. Suggestions welcome, though.
Also, some of the data is from the final day, rather than final tick:
Round 15
Round 16
Round 19
Round 31
