I like the idea of focusing on one because i see too often players jumping from one unto the next without really putting enough effort on that one. it is also because the "new" becomes "old" and our emotions does not get the "fixe" it demands or the "pleasure " of a new hopefull system.
having said that Dobbe is right about the spread and its advantages. placing all your eggs in one basket has its desadvantages as well.
BUT THE REAL PROBLEM IS THE FOLLOWING; even if a player has a fair enough method, he takes more time then one can master to see hard rock results by playing that one system/stategy.
what I suggest is what I play. what can get a player to the long run much faster and therefore be practical in real play.
the Cluster method as a example. 3 numbers with a main number. (wont go into details since you can find it in the "merger street system post forum".
a minimum of 25 sessions is required to get a hard rock result. if you play one cluster, or one session, it can last me 2/3 hours on a real table. a lot of time.
you can play 12, 16 sessions, be in the red. a lot of time invested and the average player can not handle the bad swings. too much to handle. some can, but most wont.
so the solution is to convert the 3 numbers and play them into streets. therefore you can easely keep track of at least 2,3, or more clusters at the same time.
I have to have a pen and paper but I can GET TO THE LONG RUN MUCH QUICKER THAT WAY.
it is "work", yes, but it is worth it. each "cluster street" must be played separately and exactly the way you would play each one.
also by playing 3 methods at the same time a player can play each at a smaller unit value and make up in "volume" of wins verses losses.
the fact is that way too often we dont give enough time for something to work. even having a winning strategy is not going to do it. anderstanding long run is the player's worst enemy.
