Sorry for the late reply

Simple millimeter paper and no proper rangefinding device? Sounds like a big "ouch" to me.

They had tables to help with this, but may have also used some form of stopwatch, there is reference made to that in at least one source.
U-Jagd is not a purpose made tool? Oh...
I honestly thought it was designed for this specific purpose. Those scales look very much like reasonable ship lengths and speeds...

What is the use for depth charging purposes? What do the scales represent in that case?

I am no expert in German, but the name, does it not stand for "unterwasser jagd" or "unterseeboot jagd"? Submarine hunting. Does it actually say if the hunting in question is for or by the submarine itself? I am curious.

By this point I am afraid to ask further. Does the Silent Hunter community actually use any historical tool correctly?

Was it any different from the US optics?
Cause for the latter, as far as I know, multiply or divide by four was the "officially endorsed" method in real life. Both for the stadimeter and the telemeter scales.

The optical zoom, does it not change the angular field of view by that factor? 4 times in our specific case?
