highest match win to round win average. (divide the won matches by rounds [ and if you want divide by total rounds played... or total rounds played that you actually won that match) (AKA average amount of rounds it takes to win a match-- in the matches you HAVE won or w/o] (interisting stat if you ask me!)
Good suggestions TRONEATER. I'll probably add the average number of rounds it takes a player to win a match first. Anything with AIs, though, is not possible
I think it is a lot more interesting if you take that divided by the round win percentage, since if you have a high match wins/round wins, it doesn't necessarily follow that you wins matches quickly. (So rounds won divided by matches won divided by round win percentage).
The second suggestion is just match win percentage without multiplying it by 7.35, if I'm understanding you correctly - lots of parentheses/brackets to follow :^).
