Carl and others,

Over the years a new measurement based system was worked out. (Carl didn't so I did); It works in a similar way as ISAF and Texel but adresses the problem points of both these systems. Problem points like : light-heavy wind shift, sloop rig cat rigged after adding a spinnaker. Singlehanding versus doublehanding.

This system is currently code named "New Measurement Based Ratings"

The latter system may well function satisfactory in the role proposed by Carl if any of you want to go that way (which I think to be unlikely)

Never the less I wanted to make you aware of the new possibility.

This forum doesn't allow me to post the working excelsheet + tabled input and resulting ratings so any body interested just has to mail me and I will send it to you.
