Point 1: You'd have to spend a lot of time at the tables to see that "many times"
Point 2: I agree - the old Poisson (and other) distribution maths will take over in the long run, but it suits the situation of the occasional trip to the casino IF you stand out the first 3-4 successives.
Again I've seen and used the principle successfully (but nothing can ever win over the casino in the long run - that longterm overrider for them is a mathematical certainty)
