So you go to the track and use three instruments instead of one?

One of things the calibration process does is to correct your own barometer to compensate for its divergence from the MSL reading you use at the first calibration.

Now given that the MSL reading you use is from an instrument costing many tens of thousands of pounds it is likely to be a little more accurate than the barometer you are calibrating, which of course is the point of the exercise.

As I am sure you know an altimeter is in fact an air pressure meter that is calibrated in a different scale but whilst your method will (may) work accurately, the electronic pressure transducer inside your weather station may well be just as accurate - you need to have faith in your instruments as these will not lead you to fly into some "HARD" clouds (rising terrain), and whilst the pressure reading on your barometer may not be absolutely accurate, the calibration process will ensure your jetting is.
