I'm pretty big on the money management aspect of poker, keeping track of every cent I have on every site, recording bankroll changes weekly in an Excel-sheet, and I have a detailed plan that I stick to when I make decisions on cashing out a profit or building my 'roll.
I don't, at this point at least, record individual sessions. I played around with the analyzer at cardplayer.com, but I haven't gotten into the habit of using it properly. I can definitely see uses for it, like having it tell me if I'm a profitable SNG player (as these profits or losses may be swallowed or defended by my cash games), or what my earning/hour is, or even if different limits are more or less profitable to me.
Once I finish my "tour of duty" (trying out the major online poker rooms
), I believe I will start recording a lot more detail. This could prove to be extremely helpful if I decide to finetune some part of my style, like playing looser, or other changes to my play.
So to the recorders here, what do you record? What have you found, later on, was useful? Or what do you wish you had been logging the whole time?
