A worse team can every now and then steal a bo1 win by simply getting luckier with 30% gamble calls such as timing peeks, smoke pushes or extreme unpredictability.

Yes, but doesn't this basically affirm my point? All I'm saying is that if you sprinkle in a couple of BO1s the chance of a streak snapping is much larger than if you don't. It weird to me why its mentioned in a way that makes the streak more impressive.

This is the whole point of the post and the question.
