There are no official differences in procedure, but of course most 
stations would try to send less information and shorter 'words' 
during slower QRSS QSOs. "73" could be replaced by "GB" (goodbye), 
and once full callsigns have been exchanged, they could be shortened 
of left out completely. Reports need not be repeated (just 'O' 
instead of 'O O O'). This is most important when using QRSS30 or 
QRSS60 for intercontinental QSOs. A useful timing advantage comes 
from using DFCW though it is slightly less readable than QRSS.
