Let me again emphasize that I compared received signal strength
(not SNR) which is a proxy for transmitted signal strength if
you believe in reciprocity.  It is true that it is not extremely
accurate due to fading, but if the half wave vertical over bare
dirt were as poor as some are saying, it would be apparent.

On 20 meters, why would I care about ground wave performance?  Only
sky wave is relevant on that band, and we can't assume that the
two are necessarily correlated.
