What does it mean when my win streak is 0?
My win streak is "zero." That is... odd. I mean, when I had a win streak of −3 that probably meant I lost thrice in a row, but zero? What does that mean?
When you win after a loss, your win streak is set to one.
When you lose after a win, your win streak is set to zero.
If your win streak is −3, that means you lost four times in a row, not three.
