"mine" vice "torpedo"

Ah, I had forgotten about the side benefit of avoiding the torpedo establishment gained by calling it a mine
The note about them being called "depth charges" was from Robert Gannon's Black may. Don't have it on me, but he wrote that FIDOs were logged as "600lb depth charges", versus actual depth charges, which were "600lb depth bombs". I'm pretty sure I'm wrong on what the weight was, though.
Faster motors on FIDO's might have caused problems due to the increased flow noise. The German acoustic torpedoes, for instance, still had their speed reduced to <25 knots from 30 for a standard electric torpedo, and those were full sized torps. Lightweight, high-speed, electric torps might have been more difficult to make. This is all speculation on my part of course.
But you're right, a faster (24kt) torpedo would still be able to catch an XXI often.
