My UL and DL values are as follows

UL: 130.13GB
DL: 250.68 GB

This seems like it might be an error, as these values are very high considering I have mostly just completed some image torrents, and a handful of video torrents.

Is there a way to figure out how these values are calculated?

I have had very bad internet for several months since joining, and can't really fathom how i could have downloaded 250 gb with such internet speeds, let alone uploaded 130GB.
