Did I? :-)

In any case, the inductance and/or reactance of the unconnected winding(s)
in the 73 material ferrite core varies with frequency. That value should be
at least 4 times the impedance of what it is connected to.

There's more info on www.fair-rite.com.

Mike, I think you mean "reactance" not inductance...
