I am not going to answer why questions .. as it will turn into a big fight about how they were tested and if that favors one over the other.
What is optimal for you is not likely optimal for me due to differences in the software. That is why experimentation in regards to settings is often very necessary with these devices.
Don't worry
Accurate measurements generally leave very little room for interpretation.
At first sight, yours just seem to contain quite a few loose ends, hence my questions.
I mainly asked *why* you chose these gain settings, you must have had a specific intention with this as part of your study?
Rob Sherwood, ARRL and Adam Farson f.i. also publish measurements.
They do this signed and not anonymously, as they feel quite responsible for the information they provide.
They are also open for debate if errors somehow slip into measurements. That is how science works and evolves.
Occasionaly this leads to parts of their work being revised for the sake of optimal "reference level" accuracy.
This forum is called Radio*Reference*.
It would be quite interesting if you would explain your measurements a bit further to make them as complete and accurate as possible.
