Yup. Everyone will treat this like a silly, “wow so dumb and pointless” thing.

It’s all quite calculated.

But the first time the loop starts, how would I ever know to edit the file?

If the brain HUD thing is new, and I suddenly am able to edit a file, I might use it for random stuff. Once the loop happens, I would have a text file with whatever random things I put in there during the previous week, with zero context.

I might be able to determine that it’s my own writing, depending on the language used.

If I’m able to tell that it was things pertaining to my upcoming week, I might conclude some kind of time fuckery; if I knew it was my own writing, but couldn’t figure out the context of when I wrote it, I might assume I’ve lost my mind.

If the former happens, that’s when I’d probably start testing; whatever day I “discovered” the file would be the reset day, I would try leaving a note to myself about the time loop and indicate the date just before that day (in the example given, Sunday before the second loop).

Once I wake up on a reset day with a text file giving me the last date before the reset and a message explaining what happens, I would know about the loop, and roughly how long I have until it happens again.

I’m a little confused by the premise.

If my memory is completely wiped every loop, how would I even know about editing this “file”, or have any purpose of doing so? The only way it’d work is if I’m given the information before the loop begins (so I always have the info, even after wipes), or at the beginning of every loop, both of which defeat the purpose of “you’re in a time loop” messages.

What am I trying to accomplish, getting out of the loop?

You can’t compare power levels across franchises that are very different from one another (Superman vs Goku type stuff barely works).

You can if you’re having fun.

Supes would absolutely smoke Goku, btw.
