PHG is relative.  The difference between 20 and 25' is 
insignificant for the purpose of PHG.  Is your
25' a "good" 25 feet?  then make it 40.  Is it a "poor"
25' then make it 20.  The difference is small relative
to someone at 80', 160', 320', 640' etc.  Remember
that you have to basically DOUBLE your height to
make even 1-S-unit difference.
