As you can see, in the MSA manual issued by the Big Three, calculation of gage R&R uses total variation instead of tolerance. Currently I have a problem in my client ( I am a consultant), since its gage R&R in several devices is more than 30%. Howeve, when I read a bool with the title "Concept for R&R studies" by Larry B Barrentine (In the book, he always mentioned the Big Three requirements as well), the calculation of gage R& R uses tolerance. And this makes more sense to me. Any body could make comments??.
