I meant more like where would you get these data from? I guess the most precise would be to actually seed a bunch of torrents to different ratios and then test retrievability after X months.

Is it possible to obtain stats what seed ratio you need to get to on average for a torrent not to die?

this is true if you manually delete the txt file.

however, just unchecking it in the client doesn’t result in a broken seeder - at least transmission-gtk 4 will write the “file.txt” even if you didn’t check its box, or transmission will create a (sparse) “file.txt.part” file if there’s additional pieces to the “file.txt” that you didn’t download.

I would expect other clients to behave similarly.

Valve locks game libraries?

Probably referring to the fact that the following text is in English (as opposed to German).

That performance curve seems terrible for any practical use.
