I'm surprised to hear that most say that within 20 to 100hz is good enough.
According to the log book, I have been working 85% CW for 32 years and I can
zero beat to 1 or 2 Hz accuracy by ear.  When working weak signals in QRN or
QRM, getting an exact zero beat is crucial if you want to have the best copy.  I
didn't have my K3 until after the 1.87 firmware, so didn't get to try it with
1.87, but if the original auto tune worked any better than the 1.92 version it
must have been very good indeed.

I've always been looking for a faster way to zero beat signals.  Thanks to
Elecraft for making it available!
