Micky,
It's not my intention to label any players as "dumb" because they use triggers based (only) on past spins. Independence is a tricky concept and we have an intuition that, because, say, 10 blacks have occurred, then red must come up pretty soon (because reds and blacks have equal probabililty of hitting). You can substitute red and black for any other bet on the table and any other number of hits or nonhits.
This intuition is incorrect.
What I'm saying is that if you believe that such triggers "work", you should test your particular hypothesis correctly. What's missing is the concept of a "control" group. Researchers working on a new drug might conduct trials in which there are 2 groups : one taking the drug and the other taking a placebo. If the placebo seems to work just as well as the drug this shows that there is no merit in the drug, yes?
In the same way, and using the above example of 10 blacks in a row, suppose you believe that this is a good trigger. What would "good" actually mean? It means after having seen 10 blacks and betting red, a red will appear, on average, within FEWER subsequent spins than when you did NOT wait for the 10 blacks. See what I mean? So in order to test a system, you need the "placebo" group in order to verify that the system/trigger actually does what you believe it will; namely, perform BETTER than the non-trigger, or a random bet.
