Came here to ask a question, but now I have a request as well. Can you give examples of where you're making money callig 3-bets? I'm down a fair bit in calling 3-bet hands.

Actually, I have an excel spreadsheet and everyday at the end of the day or end of a session I write down my end bankroll and keep track of my swings for each day. And each day I write a note about what happened, so I guess in a way that's kind of like what you're doing.
I've started copying this idea, just thought I'd ask exactly what you track. For instance I have

Movement type (mainly Session but figure I can track bonus/withdraws/etc)
Total BR
Buyins (movement amount in buyins for the stakes I play)
Comments

And then a column for each site so I can track how much is on each and I just sum those for my total BR column. Anything else you have on yours?
