If I understand you are using correlation calculations to understand variability in measurement repeatability? What might cause a difference? The equipment or measurement process?
Turns out it was due to multiple factors.. Some were multi-colored and they gave rise to detectable differences (as I sample multiple parts of a container), sometimes I didn’t make full contact (human error), and a few other trends. The instrument itself was fantastic. I’ll make a video going over the samples with poor reproducibility soon!
