There was virtually zero lead length in the measurements. The intrinsic
L is in the resistor itself.

There is a type of wirewound resistor in which the winding direction
reverses in order to cancel some of the L. I have such a resistor. It
is rated at 100w and it performs semi-okay up to about 2MHz.
