That is a tad sudden. If anything, you should let it run for a week. 2 days isn't a whole lot of time. There are likely more people who would put in their choices as well. Some folks don't bother going online during a work week for various reasons, and won't see this until today, kind of thing. As most folks have a Saturday/Sunday off type of schedule, it would probably be best to leave this up during the weekend. Try compiling the data on Monday. You may or may not have more postings, but it would be SLIGHTLY better than what is currently up now.
Just a thought on it.
