I'm not trying to be combative, but I don't understand why successive RT60 measurements would change even a little if the test conditions are identical. Now, maybe that could happen if you use pink noise as a sound source rather than a swept sine wave. In that case the change is from the random nature of pink noise.
When I did the tests for my new video I measured at a few nearby locations. I didn't note the exact distances, but the two shown below were maybe six inches apart. As you can see they're pretty similar, and very different from the "no diffusors" and "no treatment at all" RT60 graphs.
