[CQ-Contest] improving pileup efficiency (was NOT ID'ing every time)

What if the guy on the other end is having a hard time copying your call 
due to QRM, QRN, QSB, or an accent?  How many times have you not been 
sure about a call on SSB because of one's accent?  Instead of QRZ? send 
KR2Q.  Takes the same amount of effort.  That will tell the world you 
are ready for the next caller and let them confirm your call.  Some of 
the big gun contesters, especially some that go to the Caribbean, send 
their calls so fast (CW or SSB) that it tends to run together and you 
are not sure of the call until you hear it several times.  A very good 
example is Jim when he goes to ZD8Z.  He ends each contact with ZD8Z 
signifying that he is ready for the next caller and at the same time 
confirming his call.
And no, this is not butt kissing to Jim because I am still P.O.'d at him 
from when I was trying to get through to him when I was operating the 
2002 ARRL 10 mtr as SOLP SSB Unassisted from the Philippines with 100 
watts to a vertical.  He was a true 55 and steadily building but had a 
big pile up.  I was sure I would get through to him in the next couple 
of calls when one of his buddies asked him to go C.W. and he was gone.  
Never heard him again on SSB.  Still need ZD8 in my DU log for a new 
zone, mult, and country.  Have him on just about all bands from the home 
call, but none from DU Land.
