Do you use raw NOAA data or GFS + validation using other meteorological models? GFS afaik underestimates wind speeds, especially for higher speeds, so I would be curious to see how one corrects for that.

As far as wake losses are concerned, I suppose your regular 2.5/5 diameter rule does not apply... but why is that? Is it because wake effects do not move linearily with rated power?
