Tweaked my system a little more.

177/290 for 61% in AFL.
208/355 for 58.6% in NRL.

Both up another 1%.

This equates to POT of 18% for AFL and 13% for NRL. This is with all bets at 1.90 and no line shopping. With shopping POT goes up 2% for each.

Going to see if I can get some more seasons data.

Oh,okay.So it's actually winners keep on losing and Losers keep on winning.Hello!.No wonder you keep backing Richmond and Hawthorn.
What we are talking about is being right.At least more right than the person we are betting with.
And if we are not being right in certain areas,we must have some erroneous data.
Tweaking gives you a better POT is excellent.But is your tweaking helping you get on the right track with Richmond and Hawthorn this season?

Moe you mistunderstood. Winners don't keep winning or losing. It changes. Winners will never always win, and losers will never always lose.

When I said this I wasn't talking about Richmond, just things in general.
