If I set my RNC compressor's threshold knob to 0db, and use the
fastest attack, fastest release and highest ratio of 25:1 (in regular
mode), I notice that on my computer's soundcard meter (delta 44 set at
+4dbu input sensitivity) the signal gets limited to approximately
-12db.. This seems to indicate that if I bypass the compressor and set
the preamp gain so that the signal to the point where it just misses
clipping my soundcards input and then insert the compressor, the
compressor will probably have an input signal level which is way
higher than what it considers 0db...

What you are discovering is that 0db on your sound card is different
that 0db on the RNC. This would be typical with any piece of gear that
uses VU style metering. 0db on digital gear is the maximum signal that
can be recorded before distortion. 0db on an analog piece of gear refers
to the Nominal level, not the maximum level.

What your findings tell me is that your Delta card provides you with
12db of headroom above +4dBu.
