For those who know nothing about the USHGA proficiency ratings,
progression is more gradual than in the FAA licensing procedure so
these numbers include upgrades from H1-H2, H2-H3, H3-H4 and I
asssume includes PG as well as HG. The "entry" level ratings are
typically around 1/3 of the total sum in a month. Note that the
yearly sums decrease with time: 2003=2,455 2004=2,288 2005=1,916 (2005
may not be complete yet, but Dec is a slow month anyway).
