Yes - and thanks for the good explanation!
Good to have you here !

Do you know - as a rule of thumb - *how much* worse a real garden-variety
carbon or metal film resistor is, compared to an ideal one? And is the
difference only in the 1/f noise (i.e. at low frequencies), or is there a
a difference in the upper f range as well that is worth mentioning?
