I think it might be somewhat beneficial, but nothing close to a thorough apnea training. If you train (and rest) well you will see results. Taking the way through a hypoxic tent will either be for the athlete that has pinpointed every little detail in the training and wants to get a little extra or for the lazy athlete that do not want to train properly.

The reason for using this high altitude training would to boost your boold and I beleive that can bee achieved with apnea training. What apnea training gives you that sleeping in a tent wont is time in water and specificity. A high Hb value alone will not give you great results.
