This thiunking crosses over into so many other areas. I agree a bouncing needle can tell you a lot if you care to take the time. I used to do station repair for a phone company. I really liked using old style test equipment. I flickering needle is somehow easier to understand than some numbers fluctuating. A bit of a flicker may be ok but scrolling numbers drive me nuts.
The digital adjustments seem to imply a perfect adjustment is possible, so you keep fiddling. Or is it that you don't feel it is "quite right"? How much does that click reallyl change the setting? SOmetimes just touching a twist knob satisfies the NEED for adjustment 
.
I have often wondered why the audio output isn't just a mix of a base tone and what the target response is doing to the coils signal?
A few years ago we connected a laptop with audio software to headphone jack of a very old machine.
We were surprised at what we saw in the audio output, more than we could appreciate with our ears. We connected the same to a very new machine and found that much of the audio information was lost or not as obvious.
