Why does the crash dive go to ~70m?

Why didn't they have the crash dive depth be something more like 20m and then you can just continue to take the sub down manually as deep as you need to go after that?

That way you can crash dive in all water depths when those pesky aircraft or destroyers show up.

What i usually do is to initiate CD, then, when the dive has started (even before the boot is completely under) I select the wanted depth - f. ex. PD. I usually end up reversing the dive at approx. 25 meters.

Another way, when in shallow waters, is to select AK (flank) at the same time selecting PD (P). You do not loose much time at that.
