From Flavorwire’s “Weird Writing habits of Famous Authors”:
“Hemingway famously said he wrote 500 words a day, mostly in the mornings, to avoid the heat. Though a prolific writer, he also knew when to stop. In a letter to F. Scott Fitzgerald in 1934, he wrote,
I write one page of masterpiece to ninety-one pages of shit. I try to put the shit in the wastebasket.
I have also reproduced for you the picture Flavorwire used to accompany this quotation. I like. Thank you Flavorwire.

Also, based on what I’ve read, he wrote standing up, and he wrote description longhand but he used the typewriter for dialogue. I also remember reading somewhere that he always stopped writing at a point where he knew for sure what would happen next, so as to make it easier for himself to pick up the thread the next day.
All of that is familiar to me as well. Can’t remember where I’ve read that but it has to have been in his own writings. Maybe A Moveable Feast?
I have an idea that the part about always stopping when he knew where to go might be in A Movable Feast. The rest might be in the Hotchner book. I’m really not sure, though.
