No but you did mention manipulating micro-contrast

" Definition " -the extent to which fine detail is recognisably rendered in a print, etc. When acutance of fine detail is good, then definition is good.
" Acutance " -the contrast at the edge of significant detail, a scientific measurement of the density gradient at that point.
" Resolving Power " -the scientific measurement of the actual fineness of detail recordable by a lens, film, or developer, or any combination of these three.
Missing from that list is tonality as it's quite different, but essentially controlling development to get the best possible negatives with the tonal range you require to print from helps to improve or prevent the loss of fine detail which is controlled by localised micro-contrast, and in theory that fine detail can be described in the above terms.
However I fully understand that your own technique is about controlling the tonal range rather than improving sharpness & acutance, that comes as a naturarl consequence.
