So the result would be a GR study (so to speak) and not a hard core GR&R, which we are often asked to provide. I maintain “we” cannot do a GR&R (or GR) for someone because it is not a “specification” we can add to the data sheet but rather a study only “they” can do using our tool, their ovens and their personal, and maybe a good consultant like yourself. And even when they take the time to do it, the results, as you say, will be one “R” short of a GR&R :-) PA Rip;

One thing to note: this is accurate insofar as it pertains to crossed studies (depicted in your form and description). When doing studies with unique parts or destructive testing, you don't do a crossed study; you do a nested study. In that study, reproducibility is not assessed, only repeatability.
