I got this from a Backtest:

Tests run.. assets..
BackTest: Tests portfolio 2011..2013
Profit 41$ MI 2$ DD 10$ Capital 297$
Trades 459 Win 50% Avg +1.1p Bars 36
AR 40% PF 1.32 SR 0.61 UI 5.6% Error 23%

My Profit is 41$. Even if it was only over one year the AR should not be higher than 41/297=13%. Still my AR is 40%.
Am I missing something?
