I think that is exactly right, Evan. Failures make more dramatic stories, and so are more likely to get written and circulated. That's why it is good to hear from people who aren't having problems, as well as those who have. Don't be too hard on yourself for not having much instrumentation. While most data is anecdotal, it is still data. Every little bit helps -- it's another piece of a giant jigsaw puzzle! The only way we are going to get the whole picture is by collecting as many pieces as possible, and trying to assemble them into a whole. Certainly, many pieces of the puzzle are missing. But this can show people where additional work is needed, and where they can spend their time to "fill in" the missing pieces. -- Those who say it cannot be done should not interrupt the one who is doing it. -- Chinese proverb -- Lee A.
