"Does "highest mesh fines" give finest or coarsest rock dust? Sorry if this
is a dumb question."

A 200 screen would give 200 x 200 separations to the inch, and would be very
fine indeed. A 100 screen would be 100 x 100, and would allow coarser
material
to fall through. So the higher the mesh, the finer the material.

It all comes out like cake anyway, so you have to crush it quite a bit to
work it into your soil. Think clay.
