TPMS Very Accurate

Just thought I'd share some findings with the group. I have calibrated instruments that make it possible to measure tire pressure accurately to a tenth of a PSI. The TPMS sensors on my 2012 F10 are within .2 PSI on the front and exactly correct on the rears. The fronts are equally reading two tenths high right and left. If anyone knows a way to calibrate please share. Also since switching to nitrogen my tire pressures need adjustment about twice a year where it was almost every month with air.
