Base Plate Design Assumptions

Hello,
I am currently in the process of designing a base plate using Hilti Profis software, and I have encountered a query regarding the application of the rigid base plate assumption in my case.
Upon analysis using the CBFEM method within the Profis software, I have found that while the von Mises stress remains below the yield point and the plastic strain limit is calculated to be 0%, the absolute deflection exceeds the criteria outlined in the guide available on Structure Magazine's website (max factor of 10 for CBFEM deflection).
Specifically, the deflection values obtained through the CBFEM method are slightly more than 10 times higher than those calculated using the rigid base plate method. However, both deflection values (0.002 in for the rigid method and 0.02 in for the CBFEM method) are exceptionally low.
Given these observations, I am inclined to believe that the rigid base plate assumption may still be valid for my design, despite the discrepancy in deflection values.
Could you kindly provide guidance on whether the rigid base plate assumption applies in this scenario? Additionally, I would appreciate any insights or recommendations you may have regarding the interpretation of these results.
Thank you for your attention to this matter.
Best regards
