NorCal 40 Meets Spectrum Analyzer

I had the opportunity to put my NorCal 40 (built from a Partial Kit) on
a spectrum analyzer. The rig was built as per the manual, no "mods".

At a frequency of 7.050 MHz it measured 3.026 watts (34.81 dBm).

(relative to the output)
First harmonic: -37.73 db
Second harmonic: -52.78 db
Third harmonic: -71.96 db

No tweaking. Just built and aligned from the instructions.
BTW, I used the MRF final.

Has anyone else had a chance to measure the harmonics of their NC40?
If so, how does this compare? I know someone posted their measurements
a few days ago, but I didn't save it.
