Ok here we have a profit over 7 years of data maybe small but yet a profit, see the amount of selections has reduced by over half but the winners have also reduced, so we see that last start winners can make a profit with the above rules, lets see if we can improve this.


we will reduce the price to less that $6

This tells me price has a big difference on returns as you can see but with just over 100 selections a year i am sure many punters would become bored, lets increase the days to 14

Good strike rate but that about it, i had a look at a few other days but less than 7 looked the best, i had a look at runners from a spell but it reduced the runners,winners and overall profit.

Here i added only 4yo and up
