In early December or thereabouts, I started hosting a cash game at my home. Cheap, small, and friendly -- $10 max, reload/cash out as needed.

It occurs to me that I am still playing on the $15 I invested in that game -- and my BR is up over $300 now.

I've been trying to keep a decent statistical record of each night that I play, but I can't seem to settle on what's important information to track, you know?

At first I tracked:

location/game
buy-in
cash-out
+/-

...then I recently began reading Sklansky, and I added number of players, number of hours, and hourly rate to my record.

Are there any additional statistics I should keep? Do you think I'm tracking stuff that's not necessary?
