20% might be fuzzy, but a factor of four isn't really fuzzy. An 11/780 
runs at 5 MHz, and a 4000/30 at 25 MHz. Even assuming no improvements in 
clocks-per-instruction between the two, the results don't make sense.

The real questions are why is it that Digital got 19105 dhrystones a 
second on the VLC and and 30120 on the 4000/60, but NetBSD gets 2109 (11%) 
and 16305 (54%) of DEC speeds, and why is the difference between the two 
so different?
