That’s very true, you can use aspect ratio to compute it. Divide the target’s length by its height - call it A. Then count horizontal marks and vertical marks in the scope, dividing horizontal by vertical, call it B. Then take the sine of B/A and that’s the AOB. The attached picture is from Hitman’s optics in SH3 and is a visualization of this, great if you can visualize the % of the target showing and mentally turn that reference image in your head to match, reading off AOB on the bottom scale.

Only downside here in WP is regarding height in scope. The real graticle (forget Das Boot) was in mils for the vertical marks, allowing for a finer measurement. With the degrees in ours, there is a large margin for error at longer ranges. May be better to measure range based on apparent length as well in WP (while estimating AOB). I’ve added this calc to my excel file in my sig.
