When modeling the various networks in LEAP it became obvious that the coil DCR values really did matter in those particular circuits. Using "ideal" coils with no DCR resulted in some pretty messed up simulations.
Prior to that it was generally "0.4 to 0.6 ohms" in most of the legacy systems. That was before the days of all the notch filters.
