Anyone know what makes them so notoriously inaccurate?

A lack of federal regulations mandating their accuracy throughout
their range? :-)

Perhaps inaccuracy is induced over time, because of drift of the
resistance element. But I'd sooner believe, it's because there is no
regulation for accuracy.

Of course you would.
