running bad should be, say a winning cycle longer than your average "good run" or losing cycle longer than average will be a "bad run" .
as a player here described in a live
poker game he did not win a single hand in 3 hours. That is definitely so much bad luck, I ask him about it. he was telling that in the 1990´s he used to be a nice player but today he was horrible.
I have a good run not too long but 3 days winning almost every Tournament until the variance show up and then back to normal about 10%.
