Siege of the Diamond City playtest?

[Roquefort]

Forgive me if this question has been asked elsewhere. I searched, but could not find an answer.

I'm going to Gen Con in August and have signed up to play Siege of the Diamond City there. Am I wrong in assuming that you can't play this twice? That is, those people who play the test run at PaizoCon will receive a Chronicle sheet and will not be able to play it again at Gen Con, right?

Thanks in advance to anyone who can confirm this!

I believe the rules say you can play any scenario more than once per character,but only get credit once. Of course I could be and likely wrong.

That is correct. You can only receive credit one time.
