Oh, and the other reason I had against just leaving it was that, not only was it off by 0.3, but it was making no effort to correct that error. As fasttalker was saying, I'm guessing that error may be higher in February than in August. Or on a breezy day. Or, worse, that error may accrue instead of being constant, since it reached a "balancing point", so to speak.
