I defer to Ted's obvious qualifications in this area.  Two personal
observations, however.

1)  While climbing Mt. McKinley with 12 other people ten years ago -- most of
us in our thirties -- we ascended at an average of 1000 feet per day so that
we could acclimatize.  There was a Forest Service encampment at 14200 feet,
which we reached after 7 days on the mountain.  We all stuck our fingers in
the pulse oximeter and were amused to see that we were all around 87% - 89%.  
We were strong, we continued to climb for another two weeks at even higher
altitudes, and thought nothing of it.

2)  While flying back from Oshkosh two years ago in a friend's unpressurized
Bonanza at about 10000 feet I felt tired and not entirely alert.  This
improved when we descended.  I have no idea what my O2 sat was, but I knew it
wasn't a good situation.  Plus, it was daylight, not night.

I'm planning on supplemental oxygen above 10,000 feet, using the Mountain
High system.  Amazing how a few years changes things.  Maybe the folks whe
insist on reminding me that I'm not in my twenties anymore are on to
something..... Nahhh!

I keep hoping for a huge discount at one of the shows, but haven't seen it
yet....
