Hello all: The problem with inward and outward numeral orientation is that both are oriented about the dial center which does not take into account the place where the viewer usually stands for viewing. Optimal viewing of these orientations require the viewer to walk around the dial or perform mental acrobatics so that you are not reading the numerals from a skewed angle.
My favorite numeral orientation for most horizontal and vertical dials is neither inward nor outward, but perpendicular to the east/west line (horizontals), and perpendicular to the horizon (verticals). If you are standing south or north of a horizontal dial, all the numerals and other lettering are most easily read if they face towards you (like the print on a newspaper on a table). If you're standing on the ground, reading a vertical is easiest if the numerals are all perpendicular to the ground (like the print on a billboard). John John L.
