Thanks for the reply Partypooper.

I've had a closer look at the results and and with a couple of major filters I have turned this from a "break even" to approximately 50% POT.

Obviously, with any filters you are reducing the number of bets with the aim of improving the return. The filters I have implemented have reduced the bets by approx. 80% but has increased both the strike rate and %POT.

My only hope is this trend continues as I have only been following this method since 1st September 2009. Fingers are crossed!
