I think that the genetics for breatholding ability is very interesting in a scientific point of view BUT for the athlete who struggles for better performance it's better to belive that everybody is on the same genetic level.
Eric- your last conclusion about that all balances in the end is the same experience that I have made during over 20 years of training/competing in sports. Often the ones with good genetics can be lazy and vice versa. The "winner" in the end seems to be the one with the strongest willpower....
