Yes. ORA1 ratings are generated by the same VPP program as ORREz. It’s distilled to less ratings, blended wind speeds and less courses. (WL and Radom leg). It also gives a rating for spin and non-spin. Plus the GPR or general purpose rating that can been used as a one number PHRF rating if your club doesn’t want to deal with courses and conditions.
As Last Call points out, it’s the ultimate irony in handicap rating that most whining was relate to the subjectivity and HUMAN component of PHRF rating committees. Now ORA1 has taken that out of the process. And people are whining about removing the human component.
Get used to the fact that there are no humans involved other than plugging dimensions into the VPP. Every boat gets treated equally based on their sail and hull dimensions by the VPP. Some may think that’s unfair because their boat is different. In which case, you can appeal to ORR and make your case. Just like you could appeal to Tom Beery’s committee.
Unless one of you call Tom Beery and tell him you would like to replace him for the next 45 years. This is the rating system that we have for handicap racing.
