Sometimes I'll leave a torrent up for days and my ratio is still tiny. So it's all relative.

In that span of time you *may have potentially shared the entire file several times. Ideally to people who would also share at least as much as you did. Anything is better than nothing

you did better than most, but it really depends on the popularity of what you were torrenting. I've had stuff up for months that still hasn't hit a 1.0 ratio, and stuff that hit 1.0 after a couple days.

Depends on what you are seeding. I leave stuff with few seeds up much longer.
