[CQ-Contest] Log question

[Tom Osborne]

Hi All

In the 'work dupes-no work dupes' communiocation, one thing I've been 
wondering about.

What happens when:

1.  W7AA calls CQ
2.  W7BB answers but logs call as W7AAA.
3.  W7AA gets credit for contact?
4.  W7BB gets a NIL for wrong call?

Then later:

1.  W7AA calls CQ again
2.  W7AA goes ahead and works him again for a dupe (0 points)
3.  W7BB gets credit for a good call

Does W7AA get credit for the first contact?

Then on the next contact, W7AA doesn't get credit for contact but W7BB does?

How does this end up shaking out on the score?  Thanks and 73.  See 'ya in 
the IARU this weekend.
