If we had an accurate periscope mod with proper vertical and horizontal marks, we could bypass the buggy stadimeter and estimate range directly from the scope. The SH5 scope does not have them, i.e:

but real scopes had vertical and horizontal marks presumably for that purpose, i.e.:

yes, its from Das Boot, but I could not find a shot of a real one. All we would need would be a periscope mod with proper marks and someone to work out the math.

This way, for example, once you know warship X has a mast height of 100 feet and is 2 marks "tall" in the scope, it is at about 1,500 meters.

I presume this is how the real sub skippers estimated the range to target.

for example, from SH3:
