(Trying to) find a bright side: the distortion is still fully a percent (and then some) less than the result posted by EPZ. 
That aside, the lens still looks better than the old Sigma 20/1.8 or the Canon 20/2.8, though these were old DSLR lenses of course. The new crop of twenties is a lot better, which is also unsurprising.
