Just the normal monitor process in the Arrs and then the magic happens in qbit manage. There you can set up targets for your torrents (share ratio, seeding times, etc). Also autobrr puts me in the very first people to download a torrent, so it helps in keeping a good ratio. Cross-seed also pumps up the ratio a lot.
Recyclarr is very important for me because I am assured to request only the very best quality for the things I care.
My setup is complex but only because I invested way too much time in. You can get to 80% what I have in a few days and still get awesome results.
