The FACT is IF you use the GPR (General Purpose Rating) number as indicated on the NEW PHRF ORA-1 certificates, which is a Time on Distance rating, it can used exactly as the existing single PHRF Time on Distance rating.
Per the old PHRF rating the new GPR number is NOT affected by wind-speed or course.
Therefore using the new GPR there is NO input from the RC as to wind-speed or course type.
To quote Tom Beery:
"The General purpose rating (GPR) can be used to set class breaks and/or used as a single rating like our existing PHRF single rating system, except that non-spinnaker classes will now have a specific non-spinnaker ratings. Some Clubs may prefer to continue to use the single rating until confidence in the multiple rating system is gained."
That said the individual boat ratings as listed can and will be debated ad nauseam.
