Dwight,
Hunter was taking his run back to sea level with the .9508 factor. That's what that factor does. You divided instead of multiplying. As an example, the factored Index for Pueblo, 12.46 x .9508 gives you the sea level Index of 11.85.
Lots of people who aren't "altitude runners" get these factors all confused.
