No, I'm sure no one will, or even CAN show you such a document.
I agree with your way of thinking - if it's over the limit, it's over the limit. BUT, and a huge BUT, here's two things that helped me as far as the test is concerened - One - An experienced CWI told me "when you start measuring defects on the replicas, if it's barely above the max limit, call it acceptable". That goes with undercut, porosity, etc. That's what I did, and I passed. Not to mention that he was correct according to the practice tests I took. Two - This is simply my thinking here - that the defect were produced (manufactured/replicated) to an almost exact size. If there is undercut that was made by a mold, I have a feeling the original mold undercut tried to produce and exact dimension i.e. 1/32, 1/64, etc. Same goes with porosity. You will see they are drilled holes. I have a feeling a 3/64 drill was used to try to similate a 3/64" spot of porosity. Now, with that thinking, you have to realize that if the replicas are old, alot of these defects will be "wallered" out do to repeated measurement.
So, just do like I was told from the the more experienced CWI.
