I play online at Leo Vegas and notice during one session that following one stream might be a bad idea in some situations. I pick Red as my dominant side and aim to win two in a row using my methodology above.
Then i got a strong black side with only black numbers hitting with Red singles, not even red series of two to hit break even territorium. All Black hot numbers strike and all Red numbers or most of them was cold.
LOL even the delar mention this ...
Then my thinking process start to talk to me and i reckon if i been betting both sides, then i would have won much more then just break even at the end, as i would have taking advantage of the Black sides strikes.
So after all it might not be such a good idea to split the Red & Black by them self in every situation.
I learn my lesson and will keep this experience in mind.
Note:
I am happy with Leo Vegas, they let me observe the game with out betting during long periods of time and i still keep my video connection, i assume not all online casinos are like that, for example Dublin Bet.
Cheers
