[TCML] Measured Q vs. Predicted

I recently acquired a nice LCR meter.  This meter happens to measure Q
factor.  I was noticing that there is a huge discrepancy between the
measured value and predicted value.  I was hoping you might be able to shed
some light on this.  Lets take my secondary as an example.  This is for the
bare secondary, no topload.

Predicted:
---------------------------------------------------------------
39.7637 Ohms = DC Resistance
19.131 mH = Ldc-Low Frequency Inductance
246 = Q

Actual
---------------------------------------------------------------
38.99 Ohms = DC Resistance
19.487 mH = Ldc-Low Frequency Inductance
2.785 = Q

Now this secondary is probably not the best secondary in the world, but it
certainly is not the worst.  Is there a reason why my measured Q is so much
lower than that given by JAVATC?
