I have been involved in this type of decision making with medical
statistics and always found that it was best choose one source as a
standard (right or wrong) then rank the others behind it to be used for
filling in missing information. Then in situations where there are major
discrepancies between the sources investigate them and if a change is
necessary document it. This provides some consistency to the data and makes
comparisons easier.
