It's not quite that much, Hans. The original CESSB article was in QEX, Nov/Dec 2014, by Dave Hershberger, W9GR. According to his calculations he was seeing approximately 2.6 dB increase in average power for a given peak-envelope-power. For a KX3 running 13W PEP and, say, 4W average, a 2.6 dB increase would result in an average power of about 7.2W for the same PEP. That's still significant.

Back in 2014 I confirmed Dave's results, using both MATLAB and Keysight SystemVue to run the simulations. Somewhere around here I must have the SystemVue workspace. Dave published the MATLAB with the QEX article.
