The Speedrun Manual of Miss Witch

That isnt true, she simulated on her last attempt precisely because her simulated self died when she tried to simulate within the simulation.

Now if the system will let her get away with it, who knows? The system doesnt seem to care about these kind of things.

Yes on first part, but not exactly on 2nd part. Yes, she chose to pay the points but she knew the time of simulation before paying the points.

Let me make it simple for you, let us say she wants to know if tommorrows breakfast will be pancakes or waffles. So she writes in the book, if tommorrows breakfast is pancakes, kill yourself tommorrow. If breakfast is waffles, kill yourself after tommorrow.

Then open up the simulation screen and if simulation time is tommrrow, you know it is pancakes. If it is after tommorrow it is waffles. You know this without paying points just from seeing the simulation time.

Now remove that page from the book and rewrite it in reverse and see if time of simulation changed.

The approach isnt perfect, but it gives you a free yes or no divination.

The simlation can simulate you any time within 24 hours. So 7pm was her death and taking over at 6:25 is fine, the date is still same june 20th.

Actions in the present change the dates, her fated death time changed from half a month to a few days due to her actions in the present. She cant change the upper limit but she can change the lower limit

It doesnt matter if she distinguishes or not. All that needs to change stuff is a change of the present. Her writing in her book is changing the present.
