Welcome, balikati.
Many of us include "unnecessary details" in our logs here. For me, it's because I don't have enough room in my paper log book to keep track of all of the minutiae that are a part of the workout, whether it's the recovery (or lack of), temperature, music, etc. For others, they like to throw in stream of consciousness thoughts that might be unrelated to the session. Others keep it real short.
In other words, it's your log. Abuse it as you see fit.
