Moose, is the graph you were referring to on this page?

om1/basic.htm
The two pictures on the shutter curtain meter pattern page suggest that
the center weighting is a result of the pattern. The first pattern
would give the weighting to a strip across the vertical middle of the
frame rather than the center. So does this mean there are two methods
involved; the aspherical metering element and prism, and the curtain
meter pattern?
If center weighting exists in auto mode, it can't be from the pattern
as it's off the film.
