re: What is your estimated total wins/losses from sports betting?

I used to track all of my W/L in an excel spreadsheet. That was for all gambling (poker/sportsbook). I can honestly say that I was a winner during that period(about 2 years). It became too much to input. Between poker and playing 10-15 games some weekends the process was arduous and time consuming. FWIW I was up, but I did learn a lot about where I was dropping nickels.
