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.
