No it takes 1 win to stop a losing streak, and 2 wins or more to start a winning streak.But that first win, that also stopped the losing streak, would also be the start to that winning streak. Kind of depends on how you look at it. Whatever, not important, just thinking aloud - or I guess in text. Well, a winning streak is 2 or more wins in a row. Could easily just lose the next game. 1 win isn't a winning streak.
