Thats what nigel thinks but the other possibility is that the measurements are all wrong and so is his interpretation of them.
Please tell us everything you know about interpreting data badly, Kenjit. What you fail to understand is that my standard for bad data interpretation is very low, and you are among the best there is. Not only do you interpret data badly, but just when the world thinks you might be onto something you contradict something you said five minutes before. I mean, wow. The ability you have to be in my grill while constantly changing your point of view is a feat of shameless mental aerobics that is a site to behold.
