How much notes are woth of?

[irishken]

Personally I just cant concentrate enough on my games(2 4 - 5 10nl) to get notes so I just play my hand the way I feel its best to play.
So question to you who take notes of your opponent how much those are actually worth of, and what kind of notes you take? General [censored] like "loose-agressive" or some more specific. I should maybe try to improve my ability of focusing on game..

I know hired a low-roller to railbird the games I usually play and im paying him $1 for each good(telling me everything about how that guy plays) player profile... +ev?
