But the things they don't quite get (genuine F/H needing to find an empty spot above 1000
An example of the 'skill' required... despite CY0S claiming to be running F/H and using the WSJT-X software which DOES ONLY F/H (not MSHV) they are running it with N1MM and we 'skilled' callers had to figure out that it's not running like 'normal F/H'. I made my QSO on 10m with them calling BELOW 1000... and some made their contacts with them calling below them (to the left). It's not simple point & click and go have lunch like some think. 
Don't get so proud about that, I figured that out with only a few hours of FT8 experience.
The major confusion seems to be F/H vs MSHV and both the Dx and the those trying to work the DX are confused.
I was just observing CY0S when a friend of mine called and said he had been trying for over 2 hours to reach them. I said based on what I have been seeing for the last 15 minutes it seems like the people that are getting through are below his Frequency.
We talked for about 10 more minutes and then I heard him shout out "Finally"! He said thanks I switched from up at 1600 down to 400 and got through.
It's the same old basic tenant of Ham Radio. Observe whats happening "Listen" or in this case "Look" and then work them. In the case of FT8 it's Look for a few minutes and then press the button and go eat dinner or watch some TV.
