Ok, after downloading the Java, it works now. I've been having fun playing
with it.

I'm not sure if the action is linear with pressure, but within the range I
use doing accented pressure techniques it appears to be. But then I'm
usually looking at slope changes in Foucault test and bends of Ronchi bands.
When I modulate pressure across zones to feather the work of wearing a high
zone and blending to adjacent zones it appears to work intuitively to my
thinking of how much pressure to apply. It could be that my brain is
non-linear.

In any case I think linear is a good place to start. If you get that worked
into the program then it might be possible to add some code to adjust that
to non-linear action that might be revealed from comparison to real world
results.

One thing that I think would be helpful would be to allow an offset along
the stroke length. In other words allow the stroke to be along a radial from
the center of the mirror but with the center of the stroke anywhere from the
center to the edge.

You'll need real Java (free download).

The program so far has no provision for MOT vs TOT. I understand that 
the difference between the two is due to added pressure on a zone due to 
the added weight of overhanging glass or lap on edge or center, but it's 
not modeled here.

I could calculate the weight at each radius of the overhanging disk. 
With this, the first approximation would be to assume that lap action is 
linear with pressure. Does anybody know if this would be accurate ?
