Hello Andy, thanks for sharing, i would like if you can explain to us if on the same question (6:24) the question is what percentage of test takers gets a score more than 73 and 84?

if you have a narrow range of tolerance and if the part dimensions are on the maximum side of specificaiton how could you maintain the cpk value greater than 2
