Is there a bound on the amount of data that is necessary to adjust a prior of a given error magnitude? Likewise, if the probability is the result of a changing system I presume it could well be the case that the pdf estimates will be consistently inaccurate as they are constantly adjusting to events whose local probability is changing. Does the Bayesian approach help, over say, model fitting to arbitrary samples? Is it, in effect, an example of a model fitting strategy no more reasonable than any other?
