This info must be pretty much redundant as very few subs to my understanding can submerge 200 meters (600+ ft.), or 300 meters (900+ ft) in late war.
Is this a typo and the depth is really measured in feet and not meters?!?

Those are SH3 measurements. Then, you have to consider thermal layer, weather etc.. and learn the skills of your opponents.

To my experience(with TMO2 + RSRDC), escorts in early war can be avoided by calm sea just below thermal layer while in late war any depth is not safe if you're making noise.

Of course, with a storm on your side you can stay at periscope depth almost any time of the war. With a safe distance between you and them they are as deaf as Mick Jagger.
