You won 9-0 and 10-0 in the same day, so I would not rule out you winning a game 15-0. but nobody seems to win like that as much now with all these game engine tweeks, I won 13-0 and 17-0 in a cup preliminary when I was L7 vs L2 and ever since on the old cup system, I never come close to winning any games like that again.
