Cool cool. Relatedly - do we know if there are any situations where multiple notes can provide the same logs?

Hey all, I'd really like to try and do/optimize a 100% speedrun of this game. I assume that 100% means filling out the ship's log, but can we 1. Set a standard definition for a 100% run and 2. Maybe make a list of all the locations/logs needed so we can start optimizing?
