AIM or no AIM, I'd put it to standby while changing the squawk. You're not
supposed to squawk an incorrect code either, and if you're not on standby,
that's what you're doing while changing.

And just how glacially do you change codes? Center radar antennas
rotate at 12 seconds per sweep, terminal radars at 6 seconds per sweep.
When you are changeing codes the target on the scope coasts for
several sweeps until your new code stays the same for about three sweeps.



I suspect it doesn't make much difference as it's over in a moment.

Exactly.
