Hello. Yes, I did mean that the "normal operating position" would be
convenient if it were in the straight upwards position.  But I realize that
this guage varies widely and so "normal" is not in any one position.

I said "relatively inaccurate" because a small move in the needle corresponds
to several tens of degrees. I meant that there is no way to determine the
exact temp with such a wide needle and small guage.  Obviously, determining
exact temps is not necessary for the average driver. I just wanted to know
exactly how much the temps were in case I ever modify in the future.
