easiest to start out with the traffic light, green for bad players red for good players, when taking a note about a tendency its important to structure it, eg its no use putting calls too loose, or donkey cause that doesnt tell us anything.
something like "will set mine when too shallow v lp raise"
or "doesnt 3bet QQ v UTG open 130bb deep. minraised dry board."
is more useful because it tells
us which stack depth or situation the note applies to and when to adjust for it and when to ignore it
