[ATM] PLOP Assumptions

I don't use PLOP.  I have reservations about the accuracy with 
which any mechanical device can be built that responds in a 
uniform and consistent manner to changes in force vectors. In a 
car engine perhaps where things are relatively crude. But on a 
mirror mount? 

In examining the few multi-point cells made available to me, I am 
puzzled by the assumptions some are making in defining the size 
and material used in the pressure pads.

It would appear that many ATM's are assuming that the pad is 
distributing the force equally over it's entire area and the 
coincident surface of the mirror. Is that reasonable?

Is PLOP assuming that the pressure pad is NOT bending under the 
load and that the distributed loads are uniform?
