A 20% tolerance spec was common in tube equipment (silver band)... If you are looking for perfect readings , it will be hard to find.

The designers were apparently OK with large excursions.

    While I generally agree with this it is often not true for
resistors. If you measure a resistor in place it will measure either the
correct value or less. If it measures higher its bad. Can sometimes save
some time when trouble shooting. Caps are a different matter and
generally have to be disconnected to get a valid meaurement.
