"Best Win"

Well, ya beat me to the punch on that one. LOL. However, I can't say I agree that it should not include any win on time. Sometimes players just timeout when they know they are beaten. If that situation brought about my best win, I'd want that up there. but 1. e4 and a timeout... c'mon. That's not my best win.
In my stats, my "best win" came against a highly ranked player. However, I played 1.e4 and he timed out. Since this situation does not effect my rating, I think the site should also not list it as my best win. Just a suggestion.
