I mistyped a letter (thanks for indirectly pointing it out, fixed) and I get this flippant response. I guess this really is reddit.My real answer is close enough, I don't need to delineate on the level of bytes.
Either way this is oedantry. My point doesn't change; it depends on what kind of book you download.
Further, compression makes this all substantially more complicated, i imagine you could compress flat text down to extreme levels using a hashtable and leveraging book specifics (lack of Unicode characters, etc).
Either way, the argument is moot, most torrent clients set a minimum upload rate of 1-5kb/s.
