QTR-Quadtone RIP

Hi all,

I would like to know something about Curve Blending: where
are the limits between each zone (Highlights, Midtones, Shadows)? How
does QTR make the transitions?
For example: if I set Highlights to
Curve1:80, Curve2:20, and then Midtones to Curve1:20, Curve2:80, where
is the limit (let say: on a 21step test file), and how is the
transition?

Many thanks,

Sylvain.
