When  you pluck the string you bypass that initial force of the hammer 
string  contact and jump right to the sustain phase.  It can be  misleading.
A problem with the pluck test is that the vibrational physics of it are  
quite different from a struck string. One has to use it in its own context, 
and  to hear what it is saying by practice. The pluck test is less reliable, 
in my  experience, of the health of a soundboard, than a struck-string test, 
assuming  proper regulation and hammers.
