A colleague has found additional information about a 16th century person who has already been established with active dates.  She would like to revise the AAP to show the new information (a difference of 4 years).  My thought is that this kind of dates is inherently subjective and variable and shouldn't be changed unless egregiously wrong.  Otherwise we could have an endless series of changes.  Is that the general consensus?
