This is common, you are seeing the manufacturing spec variance or component tolerance. While some newer systems are getting close, they can still have a pound or so of variance. I don't know about the Toyota system, but some can be calibrated by the dealer once the pressure in the tires is matched with a known gauge. Hopefully someone here will know.
Originally, these systems were never intended for for measurement. They were solely for warning the driver to inspect the tires.
