I don't know how they can measure something like that, but I would not doubt it. I dive regularly with my wife, and while I have many more dives in and have been diving for longer and in more locations, I still look at her in amazement wondering why she is such a natural.

She swims better than I do, she uses less air than I do, and she notices many creatures that I completely miss. Now of course she is in better shape than me (I am 6 years older than she is), she is smaller than I am, and she has near perfect vision, while I can't see more than 1 foot without my glasses.

Anyway, I feel very lucky to have such a great dive buddy.
