My feeling is things that are overwhelmingly likely do not get treated as information. For example, Harry's clothes go with him, but "Time" doesn't consider that to be information of his clothes still existing. It feels like that there's a Deus ex Machina aspect to how "Time" works and deals with information. Sometimes when you try to time-turn you just encounter Paradox.
So based on that I'd predict that if you try to time-turn with intention to get more uses out of the stone, you will encounter Paradox.
This is a new thread to discuss Eliezer Yudkowsky’s Harry Potter and the Methods of Rationality and anything related to it. This thread is intended for discussing chapter 119.
Plans for next chapter release:
There is a site dedicated to the story at hpmor.com, which is now the place to go to find the authors notes and all sorts of other goodies. AdeleneDawner has kept an archive of Author’s Notes. (This goes up to the notes for chapter 76, and is now not updating. The authors notes from chapter 77 onwards are on hpmor.com.)
