(I don't really know anything about the math involved)
I did another google search:
"round robin tournament"
Then I tried:
"round robin tournament" +software
Quite a few hits that might help including calcuators.
Here is one link:
http://www.devenezia.com/downloads/round-robin/
I guess what I'm driving at here is others must have wanted this and their answer must be on the web.
Good luck
