For sure it has done this on WASS,
Thinking that it did it on RangePoint,
Probably works ok on RTX,
Never have used RTK.
What I am talking about is doing a dry run on the field edge,
Laying out the AB line,
Seemed to be where it needed to be,
Turn around and the line is not really where I wanted it to be.
Never had it jump on subsequent passes.
