Why can’t I desaturate on Adaptive Contrast as much as I did when I was at elevation?

Our adaptive training systems remove about 7% of the oxygen from the air. At Sea Level this reduces the partial pressure of oxygen from 21% down to about 14%, to an approximate simulated altitude of 10,000 feet.

If you use a system at elevation, like Aspen (7000 ft) you will desaturate more than you will at sea level.  This chart helps to correlate effective altitudes.
