What is accurate?

I think the answer is "it depends". There are states that a model
allows to represent and there are states it does not allow to
represent. If a device ends up in a state that the model can't
represent, then the device has a problem, From a debugging point of
view, the worst is a device in a state that can't be represented
propoerly reporting a valid state it is not in.

So like everything else, it is a modeling decision, like picking types
and everything else. I am not sure that 'as accurate as possible" is a
helpful guideline; for operational state I prefer to see as much as
possible the device's true state. (But even picking data types for
leaves restricts what can be represented, so it is a judgement call.)
