What is most affective and Efficient way of taking notes on players? How do u do it?

[fatcrap]

just note how they play their bigger hands on different flop textures, if they check raise the turn with the nuts, what kinds of flop textures they like to bluff on, etc.

I cant really rely on mine, as I write anything when im pissed... there are normally 1-2 players on my table which have notes from previous MTT's where my notes say :

- Donk
-Asshole
-Would pee in his drink
-etc...

Altough I should probably start taking effective notes lmao
