I am sure the USPN guestimated interpolated, calculated... what ever ... the rating from SCHRS or Texel.... but that's not the point. The accuracy of the rating is not the issue.

After 5 races... the provisional status changes... after 15 races ... *not regattas just races) the brackets are removed.... The USPN committee can run the numbers and adjust the F20 DPN rating...

If they do this... the rating will simply reflect your performance. The PN system is just not designed to work well this way...

My solution is just to leave the brackets on the F20 rating until a US Fleet develops and generates enough data from enough different helms for the portsmouth math to work.... Likewise for the M20's and other one of a kind boats.. (CFR 20).

Remember... it was a political decision that brackets around a rating prevented an owner from racing it in the Area Championships. That is the only practical importance of brackets around a rating.

Just let the bracketed ratings represent classes that are not yet statistically averaged (but the PN committee is collecting wind speed data)
