I'm curious to your thoughts on ways to more accurately project and predict student enrollment numbers. We try to factor in as many external sources as possible such as the legislation to expand the Post 9/11 GI-Bill, but it really feels like at it's most basic it's just a guessing game based on previous year enrollment numbers. Thank you.

In general, is there a particular number that may be considered a "good" profit margin, or are there just too many variables (size and type of business, type of industry, etc) to allow for that simple of an answer.
