Wii Fit vs. Standard Scale

I recently started weighing myself on the Wii using the Wii Fit program. I was surprised to find that the Wii Balance Board was weighing me as more than a pound less than the scale I had been using before. I've had the scale for a while, so maybe it is worn or something. The Wii board seems pretty sensitive, so I think I'm going to go with it from now on. I just hope it is truly accurate.
