Proper or instinctive design choices for trimpot direction
It seems logical to my way of thinking that CW is "forward , up, and more" of any parameter you are adjusting such as Black Level or White level which are opposites or simply "more resistance" using pins 1 &amp; 2.

The pins should be numbered "one TWO three " which also is to say the CW direction of wiper rotation from 1 TO 3.  That's always been a Bourns®  standard.
