I was looking for VPP's and Polars and ran into this:

This shows how ratings should be adjusted for light and heavy air,
using the new Americap system. PHRF is assumed accurate at 11 knots,
and adjustments calculated for 6 and 20 knots are shown in the last
columns. The two examples explained are an Alberg 35, which needs a
big boost in light air and a reduced handicap in heavy, while the
J-125 is the opposite, deserving less handicap in light and more in heavy.

For the 35s5, a large 24 sec/mile additional handicap is needed to
help it keep up with the fleet in light air, while it only out
performs by 7 seconds in heavy. Perhaps this wasn't the best choice
for light air.
