The low ρ rank observed for all models could lead one to conclude that the uncertainties are useless in distinguishing high from low error. However, we do see an on average lower error for low uncertainties and likewise a higher error for high uncertainties. For the 150k model there is close to a factor 2 in difference between the lowest uncertainty bin and the highest uncertainty bin, meaning that the probability of getting a high/low error is indeed higher for a high/low uncertainty.
