How can everyone on a private tracker maintain seed ratios above 1? Is it mathematically impossible? (lemmy.ml)

I know that private trackers require users to maintain a good seed ratio. How exactly does that work out mathematically? If a bunch of users have seed ratios above 1, does that mean that there are some users who will forever be below 1, and thus end up getting kicked out, thus resulting in the private tracker just... shrinking over time?

I just want to point out one contradiction...

You mathed out how to maintain exactly a 1.0. But you asserted, "A closed group of users can all have a seed ratio above 1.0"

You didn't show how this is possible.

A valid point, trackers often give you a certain amount of upload credit for free, and there are often other ways to earn those credits too, so all users' ratios would be above 1.0, but that should have read "A closed group of users can all have a seed ratio of 1.0" if we're looking at just the data transfer itself.
