I normally do two brackets, but I did four this year.
1st: I reviewed and selected. I came up with Perdue as the champ. This is the one I've submitted to the groups I'm in.
2nd: Was selected using a randomizer.
3rd: Was selected using metrics.
4th: Was a type of chalk bracket.
After the first round, the best so far is the 3rd 85.4%. The 1st and 4th are tied at 38.6%, and the 2nd is at 16.6%.
