Playing after a particular SD or z- score has no inbuilt advantage. It is only an attempt to get near "virtual limits" of randomness which is a fallacy than reality. Rather, waiting for such variance to occur, we miss winnings of "positive variance" whenever they occur in a session and gets very few opportunities to bet or win.
For instance, if we are betting an EC and get 1 hit in 9th spin, we have a Z-score of -2.33. If someone feels it advantageous to wait till this happens, statistically, he needs to wait till 250+ spins to get one such opportunity to bet.
There are a few so-called experts here who mislead all that playing after 3.0 STD has an advantage while there is no such thing, in reality.
