First, you need to spell "tourney" right
Seriously thouhg, I have a very similar spreadsheet that I use to track my tourneys. I don't like how PT tracks them (maybe I do it wrong, but it seems like to much of a pain in the ass for me), so I do it myself. And this gives me very nice numbers to use at the end of the year for taxes too...
Here are the columns I use:
Site | Date | Entrants | Finish | Buy In | Winnings | Net
BTW - I use 3 differnet sheets for MTTs, SNGs, and HU play. That way, you can come up with some meaningful statistics for each type of tourney, if you like... % ITM, ROI, etc, etc...
