It was my belief that the message properly decoded would read "thecolouriskeyfile", which would indicate the inner and outer colour tracks would be decrypted by following the same steps as with the height track. The British spelling of "colour" seemed reasonable because the Rob Myers guy is a filthy Canadian, and CoinArtist seemed to have EU heritage, although I couldn't find anything definitive.
Interesting -- and that would make sense too. The binary pattern we *have* is:
100110011100100001010110011010000001010010001010001001001010001001100000101010000101100100...
and the one that *would* say "thecolouriskeyfile" is:
100110011100100000100111001011011101010010001010001001001010001001100000101010000101100100
Differences in bold. Maybe they got off somewhere in transcribing the pattern.
