There was some inaccuracy involved in SC intersection points as well, in fact, as far as I can tell, intersection points in DW are more precise than they were in SC (an indication that the bearings sent to TMA, when not corrupted, are slightly more accurate than in SC).
My best guess as to what might be causing the difference is that in DW, when the TA is turning, the bearing line is off the mark and needs to be disregarded. Any intersection that line makes with a line from any other sensor is pure junk.
