Originally I used a Kill-A-Watt device to measure.

I just tested again using a high end Fluke Multimeter. The outlet pairs now
show 125V, 118V across hot/neutral, but it changes slightly every time I
measure. In fact, now the high/low readings swapped sides within the pair.

I had also changed the location where appliances were plugged in to take
advantage of the high-performing outlets, so the difference in load might
have something to do with this swapping of the high/low readings.

Now I remember that whenever I have a high load on one outlet, one of the
other in the different pair suddenly performs better.. for example I plug in
the vacuum cleaner and then the aquarium lights get brighter..

It would certainly be using an analog meter to see if it reads the
same, or proportionate to a digital meter, which I have guessed that
you used.
