An Emergency Descent, for whatever reason, probably starts at Altitude and at cruising speed. Would "10 or 15 degrees ND pitch" be the kind of pitch which would be appropriate, if an Emergency Descent were required ?
Altering from a slow (unrecognised) stall with excessive NU pitch to "10 or 15 degrees ND" would feel unusual/uncomfortable in terms of Gee. (Most people seldom experience 0 Gee, except momentarily at a fairground.)
