Interesting.
my IPD is 66mm, and if I hold my arm straight out the distance back to my right eye is about 26-27" (660-685mm) so about 10-11x.

The distance between your eyes is about 2” apart, and the distance from your eye to your extended finger is about 20” apart. How can this be useful for estimating distance?

Scenario: You are standing on a hill and want to estimate the approximate distance to where the foot trail disappears into a thicket of blueberry bushes. There is a nearby red barn, which you estimate is about 100 feet wide.

that's assuming you know the barn is 100' wide, but haven't we already established that I don't know that. hahahahah

or y'alls could just learns to use a mildot scope and guestimate distances with that.
