[Elecraft] Feature wanted for W2 wattmeter

[Alan]

The power delivered to the load really is forward power minus reverse 
power.  You can see that by imagining that you disconnect the load 
completely (infinite impedance) or short it out (zero impedance).  That 
means no power can be absorbed by the load.

The wattmeter reads equal forward and reverse power, so that forward 
minus reverse equals zero, as it must.
