The threshold value is *number of pixels* for minimum basin size. Usually it would be in the thousands. With your region size of 11 billion you probably want a threshold of tens of thousands. As Giuseppe explained previously, accumulation has been rescaled to square kilometers, therefore the threshold is ok (still a bit small, but not nonsense).
