When the boss gets the wrong impression, is there a limit to how hard you should try to fix it?

Question: “I recently had a performance review in which a couple of the things that were said about me were simply untrue. These comments took me completely by surprise, and I realize that in defending myself I probably came off as whiny and was very ineffective. Only now that a week has gone by do I realize exactly what I should have said, and how I should have said it. I got my raise and a decent overall mark, so is it just too late now to state my case? In going back over old ground, would I only make myself look worse no matter if the facts are on my side?” – May, Clerical Trainer
