Hello there,
have you tried to compare your difficulty measure with star rating ? I made a few correlation plots to illustrate this:

the "rank" is calculated by ordering the difficulty values, 1 will be the lowest, 2 the second lowest and so on.
I found it pretty interesting that it correlates with star rating so well given that they are different methods, what do you think ?
actually I made a similar analysis of beatmap diff and player skill using only score data and also got a high correlation (~0.88), so I was wondering is it really worth the effort to do this if star rating seems to be giving the same results ?
don't get me wrong, analysing score data to derive actual difficulty seems to be the best shot at getting that "true difficulty" people want but when I see those correlations I can't help but conclude that star rating seems to be pretty good already, despite not taking patterns into account.
