I don't agree that it is either unfalsifiable or unproductive. And even if it is unfalsifiable, it's not "by definition"--so often that phrase is misused to add an aura of authority, but there's no tautology here. I find your claims to be self-reflectively unproductive and erroneous.

(I would note that, strictly speaking, my statement is provably false (therefore falsifiable) since by definition nothing can be at setting 11 on an implied scale of 1-10.)

I also take issue with "I'd argue" ... so often that phrase is misused to characterize an assertion with no accompanying argumentation.

Further discussion is unlikely to be productive so I won't comment further.
