[Elecraft] IMD and supply voltage

[Bill Frantz]

And 120W over 100W gives you a whopping 0.8dB increase in power. 
Will anyone notice?

I see the "easy to measure" effect in many fields. Anything 
that's easy to measure becomes the only thing to optimize. In 
program language compilers,the speed of the optimized program is 
easy to measure so it is more important than robustness, which 
is hard to measure. In cars, horsepower is easy to measure, so 
it becomes more important than handling. In cameras, its pixels 
over lens quality. In radios, it's power over IMD. etc.
