I think the problem is that because of the size of each torrent, and there's 1000 of them, it's difficult to effectively seed all at once, so instead people would rather seed sections at once, and rotate through them.

I'm not sure how people setup the rotation though, that can't be an incredibly common feature but I could be wrong.

There are features that prioritize those with low seed/leech ratio in a sort of periodic fashion. Also it partially auto-balances because a swarm only needs a little more than unity ratio injected into it to get itself fully replicated. So each one that get's chosen because of a low seed/leech ratio will inherently drop out of that criteria as soon as the swarm is self-sufficient.
