Oh, Captain, my Captain,

I generally agree with what you say, BUT...

I kinda grew up in my father's machine shop and learned a consistent touch 
from the machinists who worked there.  As I mentioned in another sentence, 
I do doublecheck after the strings are out or at least slack.  I very 
rarely find any disagreement between the two.

The only difference creeps in when the old eyes have trouble reading the 
vernier scale on the caliper.  The vernier scale on the mike barrel is much 
easier to see. Them newfangled dial thingies are easier on the eyes, but 
with more moving parts they are more prone to wear and inconsistencies 
which call for recalibration.
