Position Tolerance with MMC and MMB

Hello Everyone

I'm curious about the way PC-Dmis calculates TP with a CF that includes MMC and MMB (Maximum Material) both on the secondary and tertiary datums.

I made an "Excel calculator" to try to compare the PC-Dmis results, but I have a few questions, hopefully you can help me answer them.

I'm attaching a screenshot from the calculator and the TP specification:



TP + Bonus - I added the TP Nominal tolerance plus the Bonus tolerance of the Feature only. Should I also sum the Bonus tolerances of the 2° and 3° Datums?

Thank you for the support.
