I'm not sure I understand the issue. Your travel in 2006 earns you status from Mar. 1, 2007 until Feb. 28, 2008. The fact that you were on the fast track and also have status in 2006 does not affect this. It seems to me that if you meet the requirements for Gold by the end of 2006, you will be Gold until at least Feb. 28, 2008.
