Am I correct in saying that while learning, the HUD values can be used as a starting point, IF I refine them after preflop action AND on the flop AND turn?
Or will this teach me a bad habit? Maybe it's best to assign the range myself and compare after the session how it relates to villain's VPIP/PFR and if I could have made a better decision using those?

Mind, I am currently grinding 2NL and there it might well pay more to just fold to strength (vs taggs/nits and mostly even loose/passives) and play the next hand.
