I can’t find what this column is supposed to mean in the Peers section of a torrent. It shows great speeds, but the speed it shows isn’t what it’s downloading at. Not all connected peers show a speed and not all of the peers that show a speed are actually downloading or uploading anything.
It is the combined download speed that the peer is getting from ALL other peers including yourself. For example, the peer may get 3/kBs from you but he/she may get as high as 100/kBs from the swarm. If you notice the figure is high, you will see his/her download completion percentage jump rather quickly.
