I do know about PEBKAC, and it would be unfortunate if that were to be the case.

Also,
 I am not using the fact, whether directly or indirectly stated, that 
"both in3 and in4 happen to report the same physical value," because 
they do not report the same physical value. Forgive me if I wasn't clear
 with my words, because English is not my native language.

For
 the record, what I have been stating since the start is that, 
apparently, I can scale the +5V and +12V monitors _only_ in in4. And 
they are not out of pure luck, because apart from researching the 
correct formula to use for the compute statements and a number of 
trial-and-error runs, the +5V and +12V values that I scaled from my 
formula just doesn't _happen_ to be correct -- they are corroborated as 
the same values that hwmonitor "sees" in Windows. I cannot scale +5V nor
 +12V from all the other inputs the kernel module provides, only in in4.

I will defer to your understanding, because you know the code much better than I could hopefully ever understand.

For
 the sake of simplicity, I have disabled my custom configuration and 
deferred to the default values provided by lm-sensors, and here are the 
results:
