Kato San, I don't see much difference in what you say and what I say below. Complexity includes everything, I think. Transforming with widely different color sequences is more complex in my thinking than comparing something quite similar. Possibly there is a better word to use than complexity. I cannot think of anything better at the moment. So it is easier to believe a measurement done by a simple transformation from very similar sequences than a measurement that is made from data far from the sequence. That is what I was trying to say. I think not too badly.
