Though the statistics aren't straightforward or necessarily robust -- the
sample size is small and not everyone attempted to make every ID -- and
the experiment is of course not 'controlled' rigorously, within those
limitations even one person (it was just one) correctly ID'ing 4 different
signals purely by chance is unlikely -- a statistician friend has
confirmed this for me. This wasn't a binary A/B/X where the task was to
distinguish A from B over and over, and where 4 correct IDs out of 4 would
not be so rare by chance. This was four different signals, A,B,C,D. You
can read about some of the analysis here

I personally find it impossible to do a fast-switch blind test of
multichannel files with my setup as it is,and did not hear any notable
difference at all between the tracks when I played them as 5.1, which is
why I was most curious to learn what aspect or timepoint people were
'cueing' from to tell them apart.
