fine =< medium =< coarse.

The formal way to proceed is to find some suitably personal metric (i.e.
the number of assembly language instructions in a task whose opcodes end in L)
and use that to divide your metric space in three.  The first part is the
light-grained tasks, the middle corresponds to medium granularity, etc.
