If it's only marked in whole volts, reading it with accuracy won't happen, so it won't be especially accurate.

How so? I suggest that you are mistaking "accuracy" for "precision". They are not even a little bit the same thing nor follow necessarily one from another.

A gauge or meter that reads (is marked) in whole numbers but is dead-on is far more accurate than a gauge or meter marked in thousandths, but is always two units off. Although the latter meter is extremely precise.

I have a metered Iso-Variac that reads in volts measured in tens, and amps measured in tenths on a 0 -1 or 0 - 4 scale. But they are 4" meters so that even very slight needle movements are visible. The human brain is pretty good at interpolation.

With very coarse markings you won't get accurate readings. End of relevant material. I have no motivation to argue over the simple and immaterial.

Doesn't that depend what you are looking for? Say I determine my LVD
should be at 11.000 volts then I would appreciate the meter being as
accurate as possible (at that point at least)?
