I saw many speedtset proof @ inv section.
I don't think speed is important for most trackers such as oink \mvd\ , few leechers @ those trackers.
It's easy to keep ratio even u have 30KB up conection, just seed long time.
I got my first 10G upload @ oink in about 3days with 60-70KB up conection before I got my VPS.
maybe speed is important for bitmetv scc.
