That 1dB is at the periphery of a radius where surface area

For broadcasters, sure. But the discussion is in reference to the
potential performance difference for ham use, and I would think that
there is more than 1 dB variation in the "other end" of the link. The
hard core DXer or QRPer digging the signal out of the noise will care,
but that's a small fraction of the overall ham population.
