It's all part of my preparation for tourney play ~ sometimes people forget to do this, and believe me it makes a difference...........gl.........
For me I do kind of the thing sometimes focusing on observation and position
irrelevant to my hand strength it's more of a training exercise maybe once, twice a week for 30 minutes.
Regarding range I analyse each player individually and stick with the rule as stated above If I've raised and get one caller likelyhood is they either have a strong spec range or unfrequently they might have a pocket pair it's rarely anything else.
Also I notice what hands they raise with and whether their range vary's depending on position - if it is they are playing optimal if it's random they are Fish in most cases, although sometimes a good player will maybe use EP to disguise range
