I think that depends on what you are testing for, Ric. Are you testing for 
everything that the fourth string might do, such as board-loading, etc? Or 
do you feel that the main effect of the fourth string is from the 
sympathetic vibration, which affects coupling and the overtone profile? I 
doubt that having a muted fourth string has anything like as much of an 
effect as the openly ringing one does -- in fact, I know it doesn't, from 
having tuned with it muted and unmuted.
