Yes, but crush depth is a depth at which sub is supposed to collapse, it's designed to it... of course it can withstand little more, but maybe little less... So I don't think anyone would dive to crush depth even if a evading torpedo, because... shipyard can't fix this kind of damage and you won't get back.
Something like diving a fighter plane below ground level to avoid a missile... or better, to dive a fighter plane, in a fog, to or below 0ft altitude to avoid a missile...
P.S. After reading the add on I see that actually we agree in general

One thing here that probably irks us real bubbleheads is that there are operating limits and absolute limits on submarines. The game deals in absolutes while we think in terms of the operational limits that were imposed on us. You have a safe range of speed and depth that work inside of. Outside of this range you are getting into dangerous areas. Too fast and too deep mean you hit your crush depth before you can recover from flooding etc etc. Crush depth is an UNKNOWN thing till you find it the hard way.

This is exactly what I had in mind writing. There are NO operational limits in game, that anyone would care about them. Maybe if game penalized after the mission if operational limits were exceeded... something like with friendly fire but not that serious. So we have ABSOLUTE limits only in game. To get people to behave realisticaly (and dive within operational or emergency limits, but NOT crush depth) we would probably have to set not exceeded in real life even in emergency... isn't it called "safe excursion depth" or something like that ? Never exceed depth ?
There is IIRC 150% safe margin in US designs between operational (test?) depth and crush depth... Or was it 175% ? I remember german standards are 200% of operational depth.

Put down that a 688i has a safe operating max depth of 800 feet (otherwise known as test depth). Crush depth is something deeper than 1200 feet but put a variable on it. It might actually be 1141 for that ship. Maybe the welders had a good day and on another ship of the same class crush depth is 1487 feet. Make it random each time you dive for each ship. That way you can not guess how deep you can REALLY go.

In game manual is written (again IIRC, didn't read it for long time
) that real crush depth is randomised each mission, so you don't know HOW MUCH you can exceed crush depth actually. However it doesn't simulate that real crush may be LESS than is written, so we should set game crush limit to something less than crush depth we want to use.
