I do understand them, Ray.  That's why the results surprised me.
There was almost no variation in light intensity over the field of
view, certainly not 2/3 stop.  It was just an evenly lit stucco wall.
I tried also partial metering over different areas of the scene to be
sure, both with the 9.5% partial in the Elan 7, and with the 12%
partial in the FTbN.  No change.  Not even a needle dip in the FTbN.

In a scene with a wide range of light intensities, yes, of course I
would expect different results with the 3 modes, and I use partial
most of the time becuase it's closest to the spot metering I wish I
had.  I can read off high and low lit areas and make my own decisions
regarding the averaging, even though the evaluative mode is remarkably
good.  

By the way, the Elan 7 has no spot mode - just CW, Partial and Eval.
