Sarah_Frantz on "Limit # of times a post displays?"

I have a query that shows the most recent 7 posts from a set of categories (offset by 7 that display elsewhere on the page). However, if a post is tied to multiple categories, that post shows up multiple times within the query... is there a way to prevent this from happening. Here's my pastebin:

Any help would be great!
