JJ,
Got a book, even read it. You might do the same...

I did, some time ago and here is what I found. Just for
you....from "The Radio Amateur's Handbook".

This is concerning the amount of audio power to modulate a carrier.

"The modulator must be capable of supplying to the modulated r.f.
stage sine-wave audio power equal to 50 per cent of the d.c. plate
input. For example, if the d.c plate power input to the r.f. stage
is 100 watts, the sine-wave audio power output of the modulator
must be 50 watts."
"With a sine-wave modulating signal, the average power in a 100
per cent modulated wave is one and one-half times the value of
unmodulated carrier power; that is, the power output if the
transmitter increases 50 per cent with 100 per cent modulation."

From "Elements of Radio", by William Marcus
"It can be calculated mathematically that the average power of the
modulated carrier is one and one half times that of the
unmodulated carrier. Since this 50 per cent increase in power must
come from the modulator, the audio frequency power must be ONE
HALF the unmodulated carrier."

In other words Doc, for 100% plate modulation of a 1000 watt
carrier you need 500 watts of audio. Your calculation that 1000
watts carrier divided by 500 watts audio equals 50 per cent
modulation proves you know nothing about the subject.
