Puntz,

Understand the 80% level was variable just wanted to illustrate the kind of odds you'd need for your stake to be 80% of the targetted profit.

I'll keep an eye out for your email, reverse engineering equations and problem solving anything to do with numbers always peaks my interest. Hence why I find myself looking at horse racing in my free time and shares in my work time haha.

I'll have a squizz at your spreadsheet tonight as well if I get the chance Shaun.
