I know what seeders and leechers are, what I don't know is why it prints two different numbers for each one and what they mean :-).
To me it seems like reading an inventory list at a hardware store and finding an entry that says
Hammers: 12(47)
Do we have 12 hammers or do we have 47 hammers? What the heck is the gui trying to tell me here?
Sorry :D
The numbers just show the connected(swarm) information.
