Now that I'm on a laptop instead of a mobile phone, I will explain better.
However, now it's much much worse. Currently seeding Legend of the Galactic Heroes torrent that's 29.8GB large. As I downloaded it, I watched my share ratio shrink from 8.300 to 7.760 or so. I have since uploaded 16GB of that file and been seeding/uploading more GB via other torrent files and am now only at 7.844?
Torrent in question:
http://bakabt.me/161010-legend-of-the-galactic-heroes-ginga-eiyuu-densetsu-dvd-ca.htmlYou downloaded 29.88GB, thus with a ratio of 8.300 you would have to upload 248GB (roughly) in order to keep your overall ratio at 8.3
Since you uploaded 16GB, that means your ratio would have been 0.535 for that particular torrent. What you are doing is confusing this 0.535 with your overall/total ratio which it is not, thus you cannot simply add 0.535 to 7.760 (8.295) as this is not how it works.
So
to make this simpler, lets round everything off to the nearest whole number as we don't need exact figures just approximates (within a few GB). Upload (UL) stays the same (I assume you already did), Download (DL) becomes 30 and Ratio stays at 8.3
To understand what you need to upload to keep 8.3 ratio, you simply times DL amount by ratio (8.3). So lets see the math to this: DL*8.3 = 30*8.3 = 249
So as you can see, a ratio of 8.3 requires you to upload (approximately) 249GB on this single torrent.
If you upload 30GB you have kept a 1 ratio which means you need to divide 249 by 8.3 like so: 249/8.3 = 30 thus a 1 ratio.
To figure out what this means for your ratio, take needed upload amount, divide by DL size and you get 249/30=8.3 then divide that by UL (16) = 0.518 then again, divide by 8.3 once more to get your final total of 0.0625 which you can now add to 7.760 to get your new ratio after you uploaded 16GB and you should have 7.8825. Oh hello, isn't this number close to what you said you were at? Its different because I rounded the numbers off, but if you use the correct figures, you would get the correct result.
am now only at 7.844
In summary, the mathematical formula I just explained is as such:
Legend: DL=DownLoad, R=Ratio, UL=UpLoad, *=Times, /=Divide
((((DL*R)/DL)/UL)/R)+Ratio After Download (Obviously before you DL the torrent) = your new ratio
Edit: If you do not understand how to equate that with all the () in it, I'll break it down:
Legend: Same as above but also S=Sum (of equation)
DL*R=S1
S1/DL=S2
S2/UL=S3
S3/R=S4
S4+Ratio After Downloading = your new ratio
Hope this helps.
