Three types of data (Front, Rear, Front and Rear Total) are shown in the precision data.
The reason that the X-axis Cpk value of Front and Rear Total drops slightly even though the value
of each side (front and rear) is appropriate is that there is a large difference between the maximum
and the minimum of the rear X-axis (Ideal difference: 0). (Opposite sign) See the graphs below:

Fig.38-2(1) correction
From data Difference of Min. and Max./2=(0.027+0.004)/2=0.015
(fig40-1) 0.015-0.027＝-0.012
Enter -0.012 into the rear X-axis mounting position offset so that the Cpk will become similar
to the dotted line on Graph (1) (Correction target).
For the Y-axis: Although the graph is shifted to the negative side by 0.010 (fug40-3(2)), the FY
and the RY are so balanced that the Cpk does not drop.
It is recommended that the front offset be 0 (*); enter the rear offset only.
If the average exceeds 0.005, carry out Adjustment Step 37. In this case, enter an offset.
* Enter "0" into the front offset and adjust with the rear offset so that the Cpk will become the target value.
