I've had this monocular for a decade, and really like it as it suits me. However, I've forgotten what the reticles numbers signify: i.e. minutes, seconds, degrees or something else, as the base for the trig., which in itself isn't the issue!
I've searched without success for a PDF of the instructions, and the video doesn't make it clear enough (for me) how it's graduated.
Possibility of showing my thickness here, but all help gratefully received.
 
Do things in reverse to work it out! Use the binos to look at something of known size at a known distance (and therefore subtending an angle that can be calculated) and see how that fits with the graticules.
