I have attempted to show only posts from the lastest day. I assume this functions in such a way that it will show any number of posts but only within a certain day. I have three posts up; two from July 6th and one from July 8th. I assumed with the options/reading set to show at most "1 days" it would only show posts within the day of my least post. Since there is only one post from the 8th it should only show that post (if I'm understanding its function correctly) however it is showing all posts thus far.
