Which would make it mid 80s, or a few years after "smart" windows started coming out. Old glass does weird stuff, too. "Depression glass" is a good example.

But it works for you, and one can't argue with that. I've learned long ago that there's no "right' way to do it, there's only results. And if you get results, who's to say what you're doing is wrong? Not me!

But I'm still willing to wager $$ that removing it will up your growth & yield. Not a huge difference, but I think enough to notice.
