If you have a system which shows a profit over 12 years of the following
Horses with TAB 2, 4 and 7
Brisbane races over 1050m
Saturday only
Good track
Field size of 14
Over 12 years showed a profit of 53%POT
Would this continue?

NO, of course it wouldn't. Common sense should prevail. You've sort of shot my argument right in the foot about the profit making filters rising to the top ..... Right Vortech, 'coz of you I'm going to post the mother of all systems right here ..... next post !! |
