the thing about value is,any one mans opinion of what is value is only valid if they have an edge over the compilers/betfair public, its no good me pricing up the races and seeing in my tissue big bucks at 4/7 and getting the world on at evs, because im not qualified to price it up as a judge.
On that basis, how do you ever have a bet? Very few have a long term edge over the compilers/exchanges. I certainly don't. But I can have a bet because
a) I rarely bet on horses and it is nothing more than a punt ~ long run hardly comes into it.
b) I'm not offering my tips to anyone under the guise that I do have an edge
c) I'm not qualified to do a lot of things, but I have to go through life backing my judgement in some areas, seeking advice from those that are qualified in other areas, otherwise I'd never get anything done.
