I agree with Sunsally on most of the aspects discussed here. I would like to add that the 10% numbers are rule of thumb and may be different based on your situation. As an example, I'm located in a small college town next to campus. I have a local population of approximately 20,000 and a college crowd of about 8000. Because the locals don't like to frequent where the college kids hang out, my local business is at most 3%. My college business is closer to 25%.
