Ooh I'm not saying you are making anything up. By saying hard to believe I mean it seems either some sensor or something isn't reading right, or IAT's on top mounts aren't as bad as everyone makes them out to be.
One other thing with my IAT's is that I haven't made it to a track yet, so all my readings are on a wot pass immediately after decelerating on the street. The more reading I do I'm finding that decelerating seriously increases IAT's and heat soak.
Not sure yet if the OP and I need to change anything yet, or not.
