I think its interesting how people choose to look to internal reasons of why the "real" world should be special to them and to them alone.
Mr J's comment of "so dont tell betting strategies are worthless....they are to most, but given the RIGHT attributes, a smart player CAN use it to make a very attractive profit" is interesting in that he states that even though betting systems don't work for most - he is special and therefore some "magic" applies to him. Mr J, don't get me wrong, I'm not trying to insult you are being sarcastic, I just see this alot, the feeling that there must be some "magic" that I can tap into.
There's no magic in the world! ( Unless you want to get metaphysical and say that mathmatics is the magic of the universe, but that's a whole different topic... )
Now, I am certainly no expert but from what I hear Mr J has played for about 8500 hands ( 85 sessions at about 100 hands per sessions ). I'm been modifying some software recently and when testing it I'll run short 20,000 hand runs. These runs are not near enough to get into the long run and often show flat betting basic strategy players having a positive return. Of course when run over 2-20 million hands these returns go away and the expectation starts to center on what would be expected for the game and strategy. My point is that ( as everyone probably knows ) Mr J is not into the long run yet and seeing a short term fluctuation.
I have wondered in the past about what would happen if you always leave when you are ahead - how does that affect your expectation. But then when I thought of simulating it, I realized the fundamental flaw - that total number of hands are what really matter. We, as people, look at sessions and such; however, in reality no matter how long we play it is one continous session and EV will rule in the long run.
