I'm sure that by now, it has surpassed even the angle trisection.

This used to be my line. I just want to say that there is nothing unusual about representing the length of a boundary course to the nearest hundredth of a foot, no matter how large or irregular the parcel is. In fact, it is the standard everywhere I have worked in the United States.
If those dimensions came from a deed description or a plat, then they are probably accompanied by bearings. Include those with the description and it is likely that someone here can help. I say "likely" out of optimism, not confidence. Deed descriptions are often written by people who are not surveyors and have no understanding of the geometry they are putting on record.
