Thanks for posting your numbers! An >1.5 ratio is still great. For example I'm below 1 as I don't really get any upload on most things. They just don't seem to get snatched much.
Do you seed many audiobooks or mainly ebooks? I guess the former given your large amount downloaded.
A lot of audiobooks. When new free leech items drop, I think it's every 2 weeks, I was just grabbing all of them. And then you get bonus points for seeding. It got to the point where I get Max bonus points (99,999) in about 24 hours and then just use that to buy upload credit.
The trick to getting a lot of upload is to be one of the first people to download and start seeding a torrent. You can also automate downloading with Autobrr, that way you download something as soon as it's available, and then everyone who downloads after you is getting it from you
