It's been my experience that anything over a volt or so difference
between the ground and neutral is an indication of an overloaded or
high-resistance neutral, but frankly, with today's superior power
supply designs, it's rare for that to be a real problem.

I think your CE is totally stumped and looking for excuses.

BTW, if all devices (say, a computer and its peripherals) are grounded
together so that there's no potential difference between each other's
grounds, the neutral to ground voltage on their feed is even less important.

No neutral that has a load on it is ever going to show exactly zero
volts; it's carrying current and therefore has a voltage drop; the
ground isn't carrying current and won't.
