Giles,
If you know that a spot reading of the face is predictably a higher value
than 18 0ray, why do you need multi-spot metering at all? Just compensate
on the aperture ring (or whatever) for the half- or full-stop difference
and make the shot.
Also, if you know this one value -- caucasian skin-- with relative
certainty, why would additional data from clothing be helpful? It's hard
for me to see why this is an example of the brilliance of multi-spot
metering. Seems more like a situation in which multi-spot metering is
overkill.
