When I include a forecast thresh of 0 and fcst thresh of 20, masked over a region (EAST poly), I get the same average of precip (accumulated over a week or so) of about 13.5.  As in identical FBAR.  I'm obviously missing something - I wouldn't think a mean of 13.5 would be possible if I'm using only values >20.

What am I missing?
