As Dr Henry pointed out the word acutance (A1) was originally as defined in the early Kodak work but is now also used (A2) to mean perceived sharpness which combines this with adjacency effects (A3).
To define (A3) would need another 4 numbers to show the height and slope of the fringe and border effects.
(A2) for each film developer combination would then involve 5 numbers. IMO nobody would use such a complex label.
