Tracking wagers

[GoIrish]

I have been tracking my wagers since 2008 in a vain attempt to find some sort of pattern...

I need to commemorate this point in time where all my indeces for the year are positive:

Win %: 22.2% ---> A little above my average
Win ROI: +12% ---> Major improvement over previous years
Exacta ROI: +244% ----> Nice score in the Florida Derby is carrying me thus far

Multi-Race ROI: +9.6% ----> Mostly DDs and P3s
Overall ROI: 53.4%

I've wagered roughly 1/3 of my yearly average so far. I routinely get killed on the TC and BC races.

Does anyone else do this?
