You could calculate difficulty by having some amount of dials on engine strength (lookahead, eval complexity) and fitting them to a function of approximate strength. You could then try to plot how the position "real outcome" changes. You could also try to use different engines or otherwise introduce variance as this sort of thing can be a tad deterministic for stats
