Acclimatisation Has a Rate
The claim
Acclimatisation is limited by the rate of ventilatory and haematological change, so ascent profiles differing in rate produce different failure at the same altitude.
01Mechanism
Adaptation requires days; fast ascent outpaces it.
02Prediction
Failure should track ascent rate.
03Refutation
Failure tracking final altitude would remove the rate.
