[PVRCNC] Another SS Exchange Question

[W0UCE]

Last evening during the SS Warm Up I noticed a number of stations that DID
NOT include their own call in the exchange

Example: 
NR 62 U 78 NC versus NR 62 U W4XXX 78 NC

The ARRL 2009 Sweepstakes Rules clearly state "Your Callsign" (See 4.3
below) IS PART OF THE EXCANGE

So the question is: 
If your callsign is not part of your exchange will your final score be
penalized for using an incomplete exchange?

Better safe than sorry but it is worth asking the question:

INCLUDE your own call or NOT ?

Exchange: 
The required exchange consists of: 
4.1. A consecutive serial number; 
4.2. Precedence; 
4.2.1. "Q" for Single Op QRP (5 Watts output or less); 
4.2.2. "A" for Single Op Low Power (up to 150 W output); 
4.2.3. "B" for Single Op High Power (greater than 150 W output); 
4.2.4. "U" for Single Op Unlimited; 
4.2.5. "M" for Multi-Op; 
4.2.6. "S" for School Club; 
4.3 Your Callsign; 
4.4. Check 
4.4.1. The last 2 digits of the year of first license for either the
operator or the station. 
4.4.2. The same Check must be used the entire contest. 
4.5. ARRL/RAC Section 
(Example: NU1AW would respond to W1AW's call by sending: W1AW 123 B NU1AW 71
CT, which indicates QSO number 123, B for Single Op High Power, NU1AW, first
licensed in 1971, and in the Connecticut section.)
