[Amps] Pulse tuning

The fallacy of the whole "pulse tuning" theory is that most amateurs  
are looking at an analog meter ( averaging ) when they should be  
looking at an oscilloscope
( peak-reading ) and tuning for the most linear peaks.   You can force  
an analog meter higher while the peaks WILL NOT increase .... only  
flatten out as they hit the emission ceiling.  This is a form of RF  
compression similar to low level speech compression, and it could be  
argued that soft tubes or a soft power supply
will produce a higher average-to-peak ratio than a new tube or a stiff supply.

So, I ask this ............
In the SSB mode, do receivers respond to peak or to average power ?
