And it's a very exception to your method.
I'm not questioning your understanding of functions, which I think is pretty good, but your method.
Let me explain this, as we're both people of science and you surely have a better knowledge of statistics than me. Every time we get the very same results from entirely different samples, we in chemistry start supposing a bias. It may be in the strumentation, or in the operator, because we know it's statistically unlikely. What do we do? We switch the operator, and often even strumentation or lab, because we know it's statistically impossible. We place a great deal in that, being sure that the method is completely unbiased. Otherwise, meds wouldn't do their job, as they could be greatly contaminated by impurities, and so on.
That being said, I still think that your method is really biased in favour of intutives, for I don't know what reason. Maybe because you're a Ni dom, or maybe lack of iron logic. But if I were you, to limit the bias, I'd suppose sensor until differently proven. Take that as a friendly suggestion from my Ti.
