I agree with you 100%. It's all about the data and the ability to plot it, visualize it, and see the difference even without passing a certain statistical test.
I used one unit with one operator, and each unit was repeated 30 times on two different equipments.
Note: Each unit has 96 data points.
When plotting the data and comparing the Equipment A vs. B; I clearly see a difference; however the Calibration / PM via the manufacturer shows that both equipment as passing their procedure according to their technique via their manual.
I stalled before proceeding to other strategies (5 units representing the variation of the process, measured 12 times each, on each equipment, with one operator).
Any ideas, inputs, would be appreciated.
