768 divided by 8 will work out your max KB's per second (Thats what BT reads transfer speeds as)
768 / 8= 96kb/s
Now depending on your ISP your upload will vary from 16kb/s up to a maximum of 96kb/s (I've never seen an ISP that offers more upload than download)
So lets round 96kb/s up to 100kb/s just to make the maths easier.
We all know there is 1000kb's in 1mb. And for example lets say we downloaded a 700mb movie and would be seeding that to a 500% ratio.
So we need to do 700 times by 5.
700 * 5 = 3500 (3.5GB)
Still with me? Good...
Time it would take to upload 1mb would be 1000 divided by 100 (Thats 1000 because 1mb is 1000kb and 100 because 100kb is our max upload)
1000 / 100 = 10
10 seconds per megabyte.
So now we need to do 10 (seconds) multiplied by 3500 (The ammount we are going to seed)
3500 * 10 = 35000
So it'll take up 35000 seconds to upload that file at 100kbs.
Divide that by 60 and we get how long in minute's it will take us.
35000 / 60 = 583.33333
Now divide that again by 60 to get it in hours.
583.33333 / 60 = 9.72222222
So about 9 hours 45minutes.
Now thats if you can upload at 100kb/s
Avarage UK user has an upload of 32kb/s
33 is one third of 100 so it would take the avarage 3 times longer than your 9 hours 45 minutes.
So lets do 9.72222222222 * 3 = 29.1666666666666666666
Just a little over 29 hours, 1 day and 5 hours to upload a 700mb 5 times, and let me remind you, this is only if you have the peers to upload to.
Also lets just have a look at the latest 10 releases on TorrentBytes and there file size's (Excluding Music):
Flightplan.TC.DVDR-ROYAL
Dragonball-Z.Disc-12.TB-Exclusive
ROH.071605.Fate.Of.An.Angel.VHSRiP-LionsDen
Ass.Fuck.1.XXX.DVDRip.XviD-Pr0nStarS
World.Series.of.Poker.2005.E23.E24-LionsDen
TAITO.LEGENDS-DEViANCE
Star.Wars.EP3-BONUS.DISC.2005.NTSC.DVDR-XPDVD
Will.And.Grace.S08E04.HDTV.XviD-TCM
The.Apprentice.S04E05.PDTV.XviD-TCM
Everybody.Hates.Chris.S01E05.HDTV.XviD-LOL
And the filesizes are as follows:
4.30GB
4.38GB
1.77GB
1.37GB
932.35MB
331.36MB
174.99MB
349.38MB
174.54MB
Add the file sizes up and you get 13780MB, and divide by 10 to get an avarage, that equals 1370MB, which is only 30mb of being double out 700mb file, meaning it would take double to upload the file 5 times.
29 hours doubled is 58 hours.
2 Days 10 hours, and again the chances of having a peer taking your full upload for the whole time is slim to none. Also 32kb/s is only theoretically your max, in pratice it's only about 29/30kb/s.
Now doing that for each file you want, seeding at full upload for nearly 2 and half days would mean you wouldn't be able to download in that time (Downloading cuts your upload by a lot)
I get roughly 3-5 releases each day (Not from BT though, thankfully)
3 releases a day at our avarage size and uploading each 5 times would mean 290 hours of uploading, per day.
Over 11 days worth of uploading on the national standard upload speed for the UK.
EDIT: The LOTR Extended Edition Trilogy seed on TB was if i remember correctly about 68GB large and 4 discs for each movie. Also it was the second most popular torrent ever on there, just slightly behind Doom 3.
