thanks for your advice wesmip1, re your points raised -

- the figures provided are not backfitted, just the results of my of ratings. I have backed about 60% of them as I have use the raw ratings to create a couple of systems.

- the prices are betfair & applying commission @ 5% on all selections changes the sum figure to 1002.59.

- will have a go at the bell curve & upload a spreadsheet

just a question - at what point would you consider taking a selection method live based around the luck/edge percentages?

cheers
