i understand that the time moves on when you read pages, but my bad memory and bad puzzle solving makes me just reload the save, or just take a screenshot of each info that i've gathered (this is exatly what i did). maybe time loss could occur the first time you read a note/page and after that be free?
Honestly, my short term memory sucks. I personally had to keep physical notes of my run unique data (passcodes, coordinates, firmware, etc.) and for the really complex stuff I mad a personal step-by-step (adjusting when things went as I intended) in a digital notebook. I remember one sequence that took an entire Cornell note sheet, before I managed to streamline with newly obtained information.
