I have seen pivot tracks in many yield maps. I used to see a lot of yield data, but I don't see that much, any more. I'm travelling this week, but when I get back home, I'll look through one of my older machines and find some that I can post. I guess it is because I've seen things like this so consistently, that I have high level of confidence in the relative repeatability of the monitor.
