Averaging is clunky when tuning because BY DEFINITION a period must
pass with accumulation of individual data points in order to make a
display. IF you leave averaging on when you tune, by mathematical
definition, the display MUST lag behind where you really are tuned, by
the averaging period.
I understand the explaination as the PTT acting illogical. And yes, no other
rigs act like this. I believe this is a carry over from several years ago when
an update was made that fixed an issue that even in PTT mode, if the key was
hit it would actually transmit. Now at least it doesn't
a good solution (for me ) could be to freeze the averaged signal for the
seconds of tuning and moving the frozen signal on the screen. So you could see
moving your determined signal to the filter section.

This is absolutely normal when averaging is turned on. Each time you
change frequency the P3 has to restart the signal average, since the
data it is receiving has changed.

This is not specified, but to be safe, I'll say after. However, I've
observed very little additional drift during warmup. This is a TCXO,
not an ovenized oscillator, so it would tend to correct for all
temperature changes whether due to internally generated heat or
ambient changes.

I think some of the microHAM units might do this. My MK2R+ advertises this
capability.
