Thanks for the suggestions, questions. I must alter my statement above:
Out of concern for possible risks of people, and a preference to not answer questions with questionable answers, I have to refrain from giving more detailed information, at least until I have proven effectively to myself whether or not the ARC holds water.
To not test it, is failure; to cheat, is also failure; whereas to test it and find it doesn't work at all is success (though inconclusive); and of course, to test it and find it works is success and partial confirmation of the paradigm that a semi-aquatic diving-foraging lifestyle of our long ago ancestors is indeed very strongly indicated, though not necessarily at a specific time period.
Since physiologically, modern Homo sapiens (humans) differ in many small ways from our long ago ancestors, I don't expect to perfectly replicate the ARC as it was theoretically used, however results in close approximation of its estimated effectiveness and efficiency, as part of a sustainable method of aquatic food harvesting would validate further study and significance.
The who, is me, the discoverer/hypothesizer of the ARC;
the why, is because the discoverer determines the validity, while others may then test both the test replication and results replication.
So, now I wonder how, when and where I'll test it.
Obviously, Safety First. Not so obvious; how does one train for sneezing? Sneeze Tables?
