Ok, here's my stab in the dark at this one.
We're all assuming that the two results are "triangles" that are the same
shape, but they're not. The two triangular pieces of the puzzle have
different angles. The smaller (dark green) one has a gradient of 1: 2.5000
while the larger (red) one has a gradient of 1: 2.66667. So the top line of
the "triangles" when all the pieces are put together look straight - but in
reality we have a 4 sided or an 8 sided polygon. I have exacerbated these
angles to illustrate my point (see attached <solution.gif>).
Anyway, that's my theory and it makes my Monday a lot better to think I
solved it. I haven't actually measured any of this, but its good enough for
me.
Anyone care to agree or disagree?

Hi mappers:
Thought I'd get your Monday off to a good start. Perhaps this explains
some of those region miscalculations? Any comments?
