I think I'd group Winner / Runner-up / FTD / Victory in one category, and number of wars / number of turns in the Clover category, but that's just me.
Another thing I'd like (actually would be more interested in) would be to compare the picks with the AH data.
No need to do as I'd initally started with (that is, determined from the AH the "best picks", and use that instead of the actual result): simply run people's picks over the 20 results and see you got most points.
