@frostygrin I think you might have things a bit mixed up, though I'm willing to listen if you think I'm wrong about the following....
The buffer is how much you can download before you reach your own minimum ratio, which is never higher than 0.8.
Your total download on the site is used to set your Base Daily Limit for downloads. You also get extra download slots which are calculated by multiplying that BDL by how far you are above your minimum ratio. By the time you've downloaded more than 800Gb from the site your BDL is already 100, plus your extras for the ratio bonus, plus extras if you've uploaded in the past.... I doubt there are many people downloading that many torrents each and every day, even with a seedbox.
What I was trying to say is that a seedbox is a great tool for fixing a poor ratio, and for giving yourself breathing room, but people shouldn't feel like they need to chase ridiculously high ratios just for the sake of it. It's better to put yourself in a good position, and then if you have things that you want to seed then you can still seed them without the use of a seedbox, and saving some money in the process.
