No problem with that. We sure need definable standards. My point, on the 
other hand, is that no matter how carefully or accurately we set A, it 
will rise and fall with the heater or AC cycle, and never be on pitch 
except in passing. This shows up easily during the tuning as you do 
interval checks.
