On the inside of the lid of a VB stubby it says "This VB was taste tested six times before we bottled it" ..... that's verbatim.

I certainly hope they didn't backwash ......

Based on my premise that you must allow for ONE bad / unlucky run, (any more than that and the nag may be out of form), then most of the statistical systems with strict parameters as their base (such as first 4 in last 4 starts, or last 4 runs = no more than 9, or must not have finished more than 3 lengths from the winner at any run within it's last four runs ..... etc, etc, etc) CANNOT show a consistent POT because a) they'll be overbet and / or b) they're far too restrictive in their nature and miss out on what SHOULD BE a system horse other than that ONE bad / unlucky run ..... if that makes any sense !!

ie; You're missing a "system" horse because of ONE bad / unlucky run.

I think you need to ask yourself, "What is it I'm looking for in this particular system ?"

More this arvo .....
