Photoshop: Simulate Graphite: Darken blending mode logic not real-time enough

Graphite build-up mode for brush tool. (Or fix "bug" with Darken and Color Dynamics)

Stylus pressure must exceed a relationship with the brightness of the applied color and the pixels being painted onto.
You can already almost achieve this with Color Dynamics set to Fg/Bg color and Pen Pressure and brush blending mode to Darken but once you exceed the darkness of the canvas you will be allowed to reduce the pen pressure while still not lifting the stylus and a brighter value will be drawn to the canvas despite Darken blending mode being active.

I guess this may be viewed as a bug and fixing this issue may provide a perfectly workable simplistic graphite buildup effect through already existing settings.

I made a video demonstrating where this fails due to the Darken blending mode not being real-time enough in its logic. http://youtu.be/psAtq9rbYfg
