Will, I am starting to wonder if you have ever used a watch with a heart rate monitor. Do you know how it responds when worn loosely or over clothes? Lets say that at the start of a multiday he's got that thing on nice and firm but as the days go by and his body starts to swell a bit he loosens the watch. Maybe he's not obsessed about HR data loke you. He just wants to be comfortable. Then some dude starts harrassing him about the data so he starts sinching that thing tighter again. Doesn't that sound reasonable?
Then the question would be why he's getting uncomfortable during runs when there are witnesses, or on the first day. And why this consistently happens to him across multiple years with multiple bits of kit in a specific way, and why this has never been an issue during official marathons etc, nor on long training runs.
He's running most of this thing topless anyway.
These are all explanations that need to be entertained, but the sheer volume of coincidental occurrences are the issue.
