Re: 1200 ft vs 6800 ft elevation
From this altitude-barometric pressure conversion site:
At 9000 ft, the standard barometric pressure is 74kPa (554 mmHg). This means that there is 73% of the oxygen available at sea level.
6:45 = 405 sec
5:16 = 316 sec
316/405 = 78%
Close to a linear relationship to available oxygen(+6.8% error). How many days apart did you do the two?
I am curious as to what your time would be at an intermediate altitude.
