2022.1SP6 Parallelism issue

I have 2 planes, PL1 is datum A (primary using minimax), and PL2 constructed from 7 basic scan/circle/plane. (least square, but it shouldn't change anything !)
Using geotol, it gives 7,1 µm
using legacy, it gives 35,1 µm
using assignments (ASSIGN/V1=DOT(PL2.HIT[1..PL2.NUMHITS].XYZ-PL1.XYZ,PL1.IJK) , then ASSIGN/V2=MAX(V1)-MIN(V1)), it gives 36,1 µm.
Then, constructing 7 planes from scans and construct a plane from their centroids, it gives about 8 µm (so I'm wondering if geotol uses them to calculate instead of hits ?)

FCF parallelism (and perpendicularity) has reported much better than the individual hits indicate for years (most PC-DMIS versions). Congratulations, very few people question near-perfect numbers.

How do you figure? I use CADGRAPH=ON and TEXT=ON and the results always correlate with what is reported. And when using Legacy, the results have been very similar...
