I am glad there are folk around the world betting "strategies" like this to keep the books in business and my profits rolling in.
It is true that human beings are not inanimate objects and such things as "reversion to the mean" apply to our interactions in, say, the stock market and property transactions.
So it is not quite as daft as saying this table has hit 5 straight reds, the next one must be a black.
But not far off. Unless there was some kind of solid connection between these different games which would cause the players concerned to approach their game differently becasue of what had gone before, there is no reason to support this sort of theory.
If it has worked in the past, then following the same logic as the theory itself, it is now DUE to fail.
Very occasionally I do bet against teams and players who have had big winning runs, where there is evidence of complacency setting in and the prices available on the dog have got to the ridiculous stage.
But this in no way is based on what other teams and players in totally independent games have been doing.
