Decreased Breath Hold at Altitude

So, I just moved from sea level to 7,500 ft (2286m) of elevation. That is a reduction in atmospheric pressure from 101 kPa to 78 kPa. Effectively, a 22.7% reduction in oxygen availability. As you can imagine my max breath hold capability has dramatically reduced in this time period (45.3%) @ 3 days of acclimation!
Wondering if anyone has seen any research on what the expected performance drop would be? I would have hypothesized a 1:1 linear relationship.
It will also be interesting to see what breath hold times will be like at 15 and 30 days.

Since the body is going to produce more EPO and red blood cells your performance will probably increase in the next weeks while the pressure is constant. However, as soon as you return to the sealevel you should notice improved performance to the prior level. Are you actually diving at that altitude right now?

Not actually diving, just dry training.
