Hmm. I think the 'more-bottled-O2, sooner', is a major factor that anyone should take into account when judging the success of Alpenglow's methods. In fact, from a clinical perspective, it totally muddies the waters for studying the pre-acclimatisation tents. How do you discern where the benefit, if any, came from?
But either way, if people want to do it, want to pay for it, and they're not sending more Sherpas through the icefall to achieve it, then I say good luck to them. There are worse things happening on Everest every year than this.
