My point about hht-x is the subjectivity. If x goes from 1 to 5, there's 5 levels of subjectivity to deal with and calibrate. I've no issue with hhts generally.
But the 1 to 5 thing is pointless drivel, not to put too fine a point on it, for getting help or describing an edge

If someone says to me I'm only getting hht 2, say, I still need for them to describe in words what is happening. So what's the point of the numbers?
By all means use numbers if you want for your own internal reference.
Anyway, there's no need for apologies or agreeing to disagree or any of that. We're adults having a debate. Normally I try to choose my words carefully so as to impart a non confrontational tone, but clearly I didn't manage it this time. Maybe I'm just getting old and cranky
