Isn't this part of why TT provided AGC slope in the RX menu? I find
that, depending on conditions, either 1:10 or 2:10 allows me to separate
signals rather well in a pile-up. A strict adherence to
AF-gain-high/RF-gain-low acts to minimize AGC action.

You WILL have AGC compression unless RF Gain is throttled because the AGC
threshold will be too low.
It's a simple matter of how much audio dynamic range you want to present to
your ears. You have to make that determination first and then from there,
set up the rig's RF/AF gain distribution properly. I'm evangelizing for a
wide audio dynamic range (with headphone listening) and my comments should
simply be seen in that context.

Why wouldn't just setting AGC to medium or slow solve all the problems you
are trying to fix. That way you never get blasted, you don't have to find
a very strong signal to set audio gain, you never get AGC compression on
speech, and you don't get band noise between words.

But the biggest problem with the scheme of using high audio gain and low
RF gain is you can still get blasted by a very strong signal as you tune
the band.
That's why the very first step was turning RF Gain to full max, tuning in
an s9++ signal and setting the AF Gain so the signal is comfortably loud.
You leave the AF Gain right there (always) and you never get "blasted."
All
adjustments after that are with RF Gain.
