That is where we disagree.  If I could "reproduce" the measurement,
then I would just make the measurement myself and I would not need the
data from you.  

I need a reasonable approximation for a realistic power consumption. 
I think everyone understands that power consumption is a function of
what software/hardware is running at the time.  The number in the data
sheet is meaningless (literally since I don't even know if it is
accessing Flash or RAM) and has no value in estimating requirements
for a power source.  I don't know if I need to provide 50 mA or 500 mA.  

If I can't come up with some sort of number to allow me to size a
power supply, I'll just use another MCU that provides better data,
like the OKI parts.
