Very small sample size, but interesting study. Correct me if I'm wrong here, I only skimmed the paper, but the theory seems to be that INTERMITTENT exposure to pressure change (simulating altitude up and down) can speed up acclimation? While the theory seems intriguing, it involves a lot of time and effort (30 hrs?), more hours than most people will spend planning the logistics of their Whitney hike. Correct me if I'm off.
In a perhaps related phenomena, I find INTERMITTENT doses of compressed O2 taken from a small pocket-sized oxygen canister to be EXTREMELY helpful while climbing above 10,000 ft.
