Mike, yes, I seems that Oxford is being accused of over-emphasising the probable error in a date determination. In my experience this never did any scientist any harm. The example case seems contrived and the re-appraisal (if needed) of previous real cases (if OxCal found "wanting") could be quite complex.
Tony, would you agree that whilst people should be aware of the dispute,
that even in this carefully picked example, the difference is only
between a probability of 50% or 33% for the particular date.
