Because I do 99+% of my wagering thru an ADW, it is very easy for me to determine my profit/loss with regard to my wagering. For the remaining less than 1%, I maintain an excel spreadsheet and merge the results with the ADW reports.
Unfortunately I am reminded that a more-realistic determination of my profitability (or lack thereof) also requires the identification of other out-of-pocket expenses like the cost of the Racing Form, gas to travel to/from the wagering location, etc.
