Why do measurement results appear differently on different computers?
The first image is the measurement result on a laptop in the garage, and the second image is the display of the same measurements/files but on a home computer.

The screenshots show the results of the subwoofer and midbass phase measurements.

The more recent build has an improved phase smoothing algorithm.

Thanks for the clarification.
Can I consider the measurements on the garage laptop to be accurate?
Or do I need to remeasure them using the latest version of the program?

The measurement is the same, just better handling of smoothing.

I don't really understand what "smoothing processing" means. I understand perfectly well that the phases of the subwoofer and midbass speakers should match throughout the maximum range of their combined operation.
 
Deep notches in the measurement due to reflections cause complete phase rotations over narrow frequency ranges. The more recent version does a better job of removing those effects when the measurement is smoothed.
 
Now I understand what you're talking about. Thank you very much. I'll reinstall the new version instead of the old one and repeat all the measurements.
Good luck to all of us in this Life!
