That being said, the one thing you seem to catch my attention about was time and material removal rate.  I am always sensitive to time, and I don't know how you could improve that except by employing mechanical means to assist in at least the rough/coarse part of the process.  The problem I see with mechanizing the fine finish is you might need fairly fine mechanical bits.

    All this talk about flat rocks has pushed me right over the edge . I
just ordered a 9 x 12 x 2 surface plate ... supposed to be within a
tenth which is probably closer than anything I'll be doing . And just
over 60 bucks delivered .

Back when Enco had a store I bought a granite 12" x 18" surface plate from them, and used it a little on the electro-optical projects from work that I took home to design while machining. After retiring I haven't touched it, the mill table is my adequately flat surface.  I might make an oak stand to use it as an end table.
