Thanks, Bugmagnet.
I believe that the "Time Left" only indicates the estimated time to finish a torrent you are downloading. It is not related to any seeding time.
My testing is indicating that "Time Left" is equally applicable to seeding. It looks like it uses various metrics to calculate a remaining time until seeding will stop. This is most clearly shown in the "Details" tab of the selected torrent.
Here is a seeding torrent where the upload ratio limit is set by the category "Long Term Seeds" to 2.00. Tixati does some clever calculation and determines that seeding will be complete in 15 days:
Here is the same seeding torrent where the category has been changed to "Test", which has the upload ratio limit unticked. In this case, the torrent's upload ratio limit reverts to the default setting of 1.1. Tixati calculates that the time left with this ratio limit is 9 days:
I do not normally use any ratio to stop torrents, so others might be able to give more advice on that. I do think that if the category seeding limits are not set, then Tixati will fall back to the global defaults.
Yes, this appears to be the case (as shown above), and I think it is a sensible thing to do.
And it appears that the highest upload ratio for the stop function is 100. Maybe the DEVteam can define 0 to be "nonstop" to override the global limits?
I do think there is a case for there to be additional valid options for the Upload Ratio Limit parameter. I would find a value for nonstop/infinity very useful. (It's why I started this thread.) But I'm thinking that a value of 0 might be ambiguous.
Would this work?
Upload Ratio Limit
Stop on upload ratio at or above:
(Radio 1) Default // the same as having the existing setting unticked
(Radio 2) No limit // forcibly setting it to have no limit regardless of the default setting
(Radio 3) {numerical value as it currently exists}
