Newport also mentioned the same once w respect to humidity. Shortly after, I came across info which reported this to not be quite exactly the case. Can you (or N) provide any links to support this comment? As you know, it gets pretty humid here and seeing you reiterate Newport's remark has me concerned enough to wish to nail down some bonafide documentation.
If that's hard to locate, no prob. I can easily do more asking around and hopefully gather a better or more confirmable consenus.
