I'm obviously not a psychologist, but don't they learn how to psychoanalyze people from books, video, and lecture? Some might call that a distance. Also, I'm not claiming to diagnose him with anything clinical either, just have enough empathy to understand what frustration looks like. Then taking the giant leap of associating that frustration and quotes like "why are you flipping now?" in reference to an unexpected result, to demonstrate he might be frustrated with some of his equipment.
Just also have to touch on how your initial argument was based on me not being qualified or within an acceptable observational range to determine his feelings on his equipment and you then follow that with "he sure seems to like throwing Luna's off the tee"
