I'm guessing there was something in your background that flagged you...not sure though from what you posted. I'm sure they have good data on those that make it and those that don't and you must have hit one of those..

The drawback is that while "generally" accurate, it occasionally grabs the innocent.

You might try emailing someone there with a question along the lines of "what would I need to do to make myself competitive?"

Good Luck!
