Cliff :
It's very easy to have 0.5 ohms (or more) contact and lead resistance with
standard probes. Try taking a measurement with both probes on the same lead,
then difference that with the reading across the coil. The result is still
only going to be good to a few tenths, but it should be better than what you
are doing now.
To really get an accurate reading, you need a 4-lead meter, or a calibrated
current source.
