This report, using the default settings, shows the ROI per year on my test data…

I see a sudden drop-off in performance after 2010.  I blame the rise of the computers.  Our competition has gotten stronger, so we have to work harder than ever to make a profit.

I’m going to drop the 2005 data from my standard back testing.  Partly because it’s old, but mostly because it makes WagerMate look too good.  I want my back testing to be as realistic as possible.

P.S. Oops, I try to remember to use the ROI switch that says “1% means a 1% profit”, but in this figure I had it set to “101% means 1% profit”.  Sorry.
