Yes one issue that has come up though is the method used to measure the
power used. Gass is pretty easy since it relies on flow, but Electricity
can be influenced by the phase of the current draw in the AC voltage
waveform, and there have been questions before on what is the most
accurate way to deal with this aspect.

Doesn’t really need to be the most accurate, particularly when
that costs a lot more. Just consistent is all that’s needed.

We arent silly enough to keep changing the meters either.
Trivial to have a test load and see what the meter claims
its taking if the consumer wants the meter checked and
trivial to charge them for the check and refund that
charge if the meter is shown to be inaccurate.

Meters have always been replaced as their calibration periods expire. It
has always been inevitable that it would reach the point where only smart
meters were available. However, at present, you can still have the smart
function disabled.
