Interesting statement. I can see where you would get that  opinion:
often, tuning each string of a unison by "stopping the lights"  (whatever the
display is) _will_ result in a less than perfect unison. Yet  I find that if
I examine more closely, using either SAT or RCT (haven't  used any other
ETD's), I will find that maybe I was hasty in deciding I had  actually
"stopped the lights." Bottom line is that I find I can tune far,  far cleaner
unisons using the device than not. And far more  solid.



No matter how hard I try, I have never been able to get a good sounding  
unison from just having the lights stand still. (SATIII). I always have to make  
an adjustment to one of the strings. Doing unison tuning by ear is described  
best by Virgil Smith. He says that the human computer can analyze the beats 
much  better than the ETD. This is evident when tuning octaves. As he put it.  
"...octaves were right on when only one string of the upper octave was sounding, 
 but was flat when all three strings were sounding".
 
One thing I have been doing lately was listen to an octave and the fifth  
above it. (C5-C6-G6). What I found was that the problem in most cases was not  
that the fifth was sharp or flat, but that the unison on one of the octave notes 
 was not quite in tune, even though initially the unison sounded just fine. 
In  fact, I even checked the unisons with the SAT, to make sure they were  
correct, but the human ear does hear it different. After correcting the  unison, 
the fifth sounded much better.
