don't know if this question has been asked yet, but does your attendance increase at a greater rate towards the date of your competition?

It's discussed a little bit in this topic.

that wasn't my question. i'm asking if like during the last week before your competition, would you get more attendance income than say two weeks before?

No, your attendees per day are only affected by the influence and number of groups performing.
