That's exactly the point :) Rather then to agree or disagree, it would be nice to have an exact figures how much it depends, on what, to a level of known error correction factor. If it happens that I am right, and GRC behave to large extent as a independent organism, that would open up a possibility to learn something new about crypto-economy. But of-course I could be wrong.
What made me think about this, is inability to collerate and predict GRC behaviour based on other cryptos, while it's relatively easy to find common related behaviors if we take any other pair.
Yet to see who is right, but have in mind that my standpoint is still just an assumption.
