Hi Robert
I note that the Nimbus 2 has a handicap equivalent to an ASW20. The
Nimbus 4DM has the same handicap as an ASG29.

I haven't noticed many ASW20's flying in open class, so I really don't
see the relevance of that comment.
What I do see is that there is (apparently) only 1% difference between
the 1960's aerodynamics of the Nimbus 2 and the 1980's aerodynamics of
the ASH26 (even allowing for the significant difference in span).
Furthermore, the Duo DIscus (again 1980's aerodynamic technology) now
has a 2% *advantage* over a Nimbus 2 (and virtually the same span).
I truly do not understand.
I would REALLY love to see how these are calculated - is the formula
published?
