From your own link:

In all normal submerged operations, the submarine is underway at relatively slow speeds. This horizontal motion through the water enables the surfaces of the diving planes to correct the effect of any slight positive or neagtive buoyancy and also to increse or decrease the submirged depth at the order from the conning officer.

I was thinking more if the flooding gets so severe and you blow ballast and still are sinking then you could have a few more of the actual safety tanks to use....instead of the dreaded ship sunk screen.Could give you enough time to get the flooding under control.

Blowing ballast means blowing all ballast. In an emergency you don't have time to play games with "how much" and "when".
ps When you do that trick of replying in bold inside someone else's quote you make it impossible to quote you again. I had to physically retype each of your replies before I could answer them.
