Tim, It sounds to me like when there is a disagreement, the computer wins.  So we may not be able to blame the computer, but we all know who the boss is with FT-X.

I'm not sure we can completely blame the computer. There is still human judgement as to whether the QSO was complete and should be logged or not.

But the basic human sensory perception of TU, "thanks" or knowing that the other guy must've gotten the exchange because he went immediately back to working others doesn't work nearly so well in FT8.

ALSO: the way folks respond to CQ's in FT8 with not just their call, but also their exchange, and the way the CQ'er broadcasts his exchange along with his CQ, these throw very basic patterns of contesting exchanges completely out of whack. And lets folks log a Q without it being completed because the other guy is broadcasting his exchange even before he copied your exchange. Now this mistaken way of operating does show up on phone and CW and RTTY too. But only by newbies. In FT4/FT8 it's just standard.

Others blame the WSJT user interface, and they have a bit of a point too. Replace sophisticated highly evolved contesting software user interface, with a point-and-drool WSJT GUI, and you shouldn't be surprised that NIL rates go up just from that.

It's a very basic statement about what is really happening with this mode.

I originally had some thoughts like you. Folks unfamiliar with logging
details or imagining a requirement for a 73 might have been the source of
most of the NIL's.

Then I asked Ed to send me my LCR and I looked it over. Most of the NIL's
given by me or given to me, were with other well-known multi-mode
contesters, not with newbies. So there goes my theory that it was newbies
racking up the NIL's.

It just IS HARDER to figure out whether a QSO was complete or not on
FT4/FT8. All the clues that even a beginning contester learns quickly, as
to whether the QSO is complete, or not complete, are simply lacking in
FT4/FT8. We make our best guess based on what the computer decodes or does
not decode, maybe try an extra cycle or two to see if we can tease out the
confirmation we are looking for, decide whether to log it or not, and
compared to other modes, that guess is several times more fallible.

And it wasn't just newbies. Even for very experienced multi mode
contesters, that guess is several times more fallible in FT4/FT8 than for
other modes.

Adding extra confirmation steps on top of the existing confirmation steps?
That'd just make the NIL rate worse because those are more opportunities
for things to get lost in the noise and QRM!

There are several contests out there (NAQP comes to mind but I'm sure there
are others) where NIL's do not result in any penalty, just the loss of
credit for that Q. I think the WW Digi organizers were wise to chose this
approach in scoring.
