Scheduling options

I recently had a problem when I posted a chapter of my story on 7th September for it to appear on the 10th, using the Scheduling options. I did this because I was going to be travelling on 9th & 10th and would not be able to get to a computer on the day I wished it to appear. The story appeared ok but by then many other stories had been posted between the Wednesday and the Saturday and so my chapter never got to appear on the BC front page. As a result it received only about 25% of the hits of the other chapters. Did I do anything wrong, or is there some way of getting over this problem if I need to schedule a story in advance on another occasion?
