I'm not sure of the methodology,  but I recall a graph from a Navy study in
which keyed envelope shape rise/decay was plotted against minimum
discernable signal strength.  Another graph depicted CW speed against MDS
conditions as well...and a third graph combined both factors.  I'll look for
this...
