Subject: [Leica] 13% or 23% ?

I'm confused by something I read in the manual for my m6 ttl.  It says that
the metering field is the 12mm spot, or 13% of the negative size, but then
it also says that the metering field is 23% of what's in the viewfinder for
any particular lens.  I think that means 23% of what's contained within the
appropriate brightlines for the lens, which is confirmed by the illustration
of the different metering fields for the different lens/brightlines.  Does
that mean that the 12mm white spot somehow meters 23% of the field even
though it amounts to only 13% of the 24x36 mm film size?  What am I missing?
