A very long time ago I read that averted vision works best when the
object being viewed is placed at either the 10-o'clock or 2-o'clock
position in the eyepiece while you look in the center of the eyepiece.

I think that's a poor system. Your scope performs best on-axis, so the
object being viewed (or it's most important component) should be
centered. Then you move your eye so that its sweet spot (which on
average is 5-10° to the nasal side, but certainly varies from person to
person) lies on the scope's optical axis as well. It makes no sense to
have the center of your vision (which is essentially blind at night)
lined up with the best part of your scope's field!
