Dean, for some reason you are stuck on the idea that the number of days you book has something to do with the date you start booking. It doesn't. Anyone can start booking on any date, no matter if s/he books 2, 3, 4, 5, 6, or 7 days. No matter what date you choose to start your 7 day booking, I can choose that same date to start my less than 7 day booking. Then we both need to make sure we call back to modify in time to keep the reservation going until we get the dates we want. I may need to make more calls depending on how far out from my needed dates I start the process, but as long as I make those calls I will keep my room from being booked by someone else just like you will.
