Yep, well understood.

Except that we know the data is from a single source.

That's what we have resorted to, with some successs now, in order
to get a solution which "looks" right (i.e. matches the paperware
two-cycle semilog chart which we must represent in code). Two
axes, scaled differently, abutted.
In no way does it make sense to me, so I plan to eyeball the two-
axis solution alongside a one-axis-log variant to try and figure out
how they differ in reality. We've backed into a solution, but I am
really unhappy with its basis (which probably explains why it took
us so long to get to it).
