I don't see how knowing the radius of an RF leg would help the crew at all with winds.
Some of the procedures I design are 400nm long...winds aloft are important. The FAA model considers all winds as a tailwind additive..(ref table 1.3 8260.52) it does not use a wind spiral. Cross winds are an important consideration that is not accounted for in the criteria, and is important at some sites.
FUGOV and MORON are waypoints at PSP.
