No not cheesed off at all. My system doesnt involve pre post odds so its irrelivant to me anyway.
I was more or less saying that picking out 1/2/3/4/5 and using them in a system i.e. run indivdual accounts on each to see if there was a profitable margin for one of those is a waste of time. As you have already said the 3rd pick might be the 8th pick by the time they jump so the stats kept are no where near accurate.......so why bother?
Now if you agree with that then why even bother using pre post odds at all? An indicator yes, however its abit like relying on a petrol gauge (thats not computerised) that tells you your running out of petrol. Ok, its a guide but when the light comes on you wouldnt be taking a guess as to what town your actually going to run of petrol in are you......
I think a good system should eliminate the guess work and be soley based upon definate goings on or set stats not presumptions like pre post odds. Bookies and punters drive the market to where it should be upon jump time not the day before when a newspaper has to meet its deadline.
