You have it backwards:

   (utilization threshold %)
       HD=0.8   HD=0.94

/32    10.9%    51.4%
/20    2.1%     31.2%

The utilization threshold for a /20 is 15 times higher for /20
but only 5 times higher for a /32.

There are some good reasons to consider a flat threshold, but as long
as we are using HD it should at least be sane.  Does anyone really think
a 50% utilization rate is opressive?
