Are you actually reading what you're responding to? I specifically talked about overdriving a preamp not the ADC.

Sorry to not pick, but just in case anyone is confused by this: AFAIK the RMS will be ~71% of a sine test tone, and AFAICT the meter in Reaper at least reflects this as well (unless it's displaying with a "display offset", which it does by 14dB by default):

Yes that is a really huge "propeller beany" nitpick.
We're talking reality, not the physics lab. Case in point, here is a 440hz sine wave where the peak and RMS are - for all practical purposes - metering the same visually. The white line is RMS...
I don't need to reduce that to scientific numbers on a chart to make that basic point between that and the gap in a snare drum signal.
That's another problem with digital recording, too many people worrying about too much minutia that has no real practical context.
