This along with the fact that using factory issue bold, thick bright lines in any of their grids causes only 80% of the corrections to stick, upon memorization. Used to have to converge Hitachis 3 and 4 complete times before all my corrections would stay in place after the mem process. There was a solution, tho it was not taught in any class I ever took.
Lowering the light level at the grid lines - be they in user or in sm or DCAM - was the answer, and I actually learned that you could do that here on the AVS, from you guys! The correct registers in there have to be amended to lower numbers - usually cutting them in half would do it, which is kinda convoluted since they are hexa-decimal - after which you would have nice, thin, totally usable grid lines to work with in your convergence/geometry, rather than those too thick, too bright lines that are factory issue. With nice thin, average light level grid lines - which match real video content - one pass would do it.
