Hypothetical (?)Shop question on boundaries

[DeVon Henne, P.L.S.]

I am working on a boundary as follows :
1. Recovered are 2 planted stone corners.
2. There are 5 courses and distances totaling about 2500 feet of woodland / floodplain boundary between the two corners.
3. The deed for the 165 acre farm dates pre 1900 and closes about 1:1000.
4. The calculated position from unadjusted deed courses between the two stones deviates from the actual position by about 10 feet (after rotation).

My solution ? create a polyline from the 5 deed courses, snap the one end on one of the found corners, scale and rotate the polyline to snap the other end on the other corner, calculate the stake out points using manual coord storage / end point snap. The results seem to to "make sense". So as not to bias any feedback on the method, I will not divulge whether or not I found any corner evidence at these points until later.

My questions ? What type of adjustment does this represent (just in case I'm asked that question on cross 20 years from now). What do my fellow practitioners think of this method ?
