Question about improving

[Jailblazers]

Pretty recently, I read one of Gigabet's posts (sorry no link) and he talked about whenever a hand, whether you are in the pot or not, goes to showdown, you should open up the hand history and try to put yourself in your opponent's shoes and see what he was thinking on each street. He said this was the way you get better.

One question though, is it worth it to do this at microstakes? BEcause most people don't take penny limits seriously, am I just wasting my energy doing this?
