If he is using a caliper, he could be measuring too much. Allow another .005 for that, and another one or two thousandths for the caliper slipping when it's pulled away to read it, and another .001 for the limit of the accuracy of the caliper, and it COULD turn out that he's actually measuring a perfectly good pin that's been turned to .020 under.
I've taken measurements like that early on in a project just for the purpose of sizing up what might need to be done, but the final measurements that lead to a decision are made with the crank out.
