Aeh, I've previously read your position about the limited value for these types of instruments. I accept that they're just a data point, not the whole set. I'm careful not to assign value to them beyond a moment in time piece of information. Moreover, since this is our first exposure to them, it's even less useful because these things seem predicated on measurements over time, making solitary instances far less useful.

But I'm not a teacher and so I have to accept that there's a limitation on how much applicable information I bring to the subject. I try to find value in what's available as I educate myself for more.

Anyway, I'm not disagreeing with you or with Irena on these things. Although, I might be less dismissive of them overall than I sense that you are.
