Steve Broyles:
Thanks for the reply and the additional information.
Using the criteria in your message quoted below, it appears that the
discrepancies between the acreage show on the plats I am researching and the
acreage generated by DeedMapper--as well as the closure errors I am
getting--are within acceptable limits.
It is reassuring to know that you will help with questions like mine.

If the unit is poles rather than chains I'd expect the measured
area to be
too large by a factor of 16. How far off is the area? If the area is
only
a bit too large (say within 20 percent) then it is a normal kind of
error.
Closure errors of hundreds of feet are the norm on parcels of 100 acres.
With experience you'll be able to tell when a parcel truly has an error as
opposed to something less sinister. Transposed digits, confusion of
digits,
and other clerical errors can lead to faulty plats.
