I assume you meant "kilocycles per second" (kiloHertz, kHz) rather than
"cycles per second" (Hertz, Hz.)

While the theory is certainly interesting, I'd like to see some comparisons
done between David's methodology and genetic analysis, which is turning up
some remarkable taxonomic discoveries of its own.  If there is a strong
correlation between the two, then David's methodology prevents a much
simpler tool to use in the field than DNA analysis.
