Unfortunately, it seems like a rather meaningless comparison, as the

True enough, though I would suggest the same would apply to the lunar
signal. The Moon isn't perfectly flat - and any signals bounced off it
have to pass through the ionosphere (twice). Ham moonbounce VHF
communications are subject to changes in propagation, and I'd bet those
effects would be even more pronounced on HF.
I would suggest the purpose of the graph was to show in general terms how
to identify whether you were hearing the HAARP signal or not, and if you
were, whether it was the terrestrial signal or the lunar signal. (or both)
