some of my favorite publications:

And the not so clear:

Is there any logical explanation for these policies varying by region??

One more good one:

Please post the good the bad and the ugly. Or just start by posting the PHRF policies from your region.

Boy, this is a really interesting topic, PteroB.

PHRF OAs (Organizing Authorities), with pretty much unlimited autonomy, seem to be able to respond to what the local conditions dictate (e.g., in terms of ratings, etc) and in this regard, that autonomy is a good thing.

When it gets dicey is when the perception changes from the local OA being responsive to objective local conditions to being responsive to local OWNERS who have some strong political clout or strong friendships with the people on the local OA. That's a bad thing.

All-in-all, my gut says let the local OAs keep their autonomy and let them make rating adjustments as the venue fits. Example: a cheater pole in the east bay of SF, Berkely Circle, for example, isn't going to be as big an asset as it would be in Naptown, where the median windspeed is probably 10 knots less than the East Bay.

That having been said, you know the issues I've brought up with PHRF Ches along the lines of the use of A-sails, so I'd say the discussion of some sort of uniformity is certainly warranted and timely.

I looked at 5 regions. The criteria for selecting the regions were simple; published on the web, regions with large active fleets.

Here is a summary of the published methods of adjusting ratings by modifying the E dimension:


Here are how these regions will impact the various E adjustment options:


I thought this really drove the point home. I don't know the sailing conditions in the North East but I would think they are very similar between each other. I am familiar with the conditions at Detroit (DRYA) and the Chesapeake. I don't see any regional effects that would indicate these variations.

Nice data set!
So, we should lobby PHRFa daPeake to conform. They are such an understanding bunch of blokes....

I would think the break point would be 3 seconds for 10% E and 6 seconds over that. That means three of the regions have an opportunity to 'conform'.

My question is how big to make the E.
