Exactly! Ask the PHRF CommitteeNobody (in the previous thread) mentioned that maybe the person should find out the history of the PHRF board of handicappers and what their latest changes were.
How do they come up with a provisional #? Is it the average of national or 'local conditions'..?
How do they treat boats that have sails with OD dims but, different sailcloth or do not follow OD rules such as a weigh in before a OD start?
Before you spend your $, it might be worthwhile to take a look. YMMV
