Since you are on the DPN committee what's the process and how does it get started?
Oh that's easy!... you need data from a buoys race lasting 45 to an hour against other rated boats (F18's Hobie 16's Tornado) The old secondary yardsticks ... Oh each boat with the same configuration (aka class legal) ... 3 to 5 of each would be a great data set. Measure the wind speed on the course over the race and average it.
99 bottles of beer on the wall.... take one down.. pass it around.... 98 bottles of beer on the wall. When you get to trashed... oh say 15 bottles into this.... you will have a provisional number. 85 more and you are good to go.
Just PHRF/estimate the numbers as you want... It's easier on the liver.
