BJ, you have touched on something that has worried me for a long time!! i.e. no matter how the selections are arrived at, they all seem to adhere to the ultimate law. i.e. all 1/1 money chances will win I dunno , about 45% of the time, all 4/1 shots will win about 20% of the time etc etc. Unfortunately it's quite sobering!!
What I'm saying is that whichever the system, whatever the S/R whatever the ave. SP, when its annalysed over a long period of time, it always seems to follow this unwritten law!!
So it's my belief (even though I bet to the contrary) that this will ALWAYS be the case over time. THe reason of course is that 4-1 is NEVER given for a 4-1 chance (well not for long anyway)
1/1 is NEVER given for an even money chance etc etc. eg. if I flipped a coin I would not give you evens, I would offer 10/11 AT BEST, you see what I'm getting at!!!! Yet we are all still convinced that we can beat the book. It is a bit like the big firms offering 20% deposit bonus, yep they know "overall" they can give you 20% and still beat you!!

Sorry thats a bit negative isn't it, let me close by saying that I've beat em' for more than 2 years!!
