Let us recall some of the rules of this project as are indicated in the blog Moly_X_25
Each person does 2.5 pages per round. So you will share a half page with someone, either the person before or after you, depending how it splits, but I would consider overlapping and not ending exactly on the edge as it gives the next person a little something to work with if that makes sense. No one's going to be mad about taking a little more or less. It all evens out eventually. Also, the second round might be confusing, because some people counted the "flap" (the page that is not really part of the accordian) and some did not.
