The altimeter on my Band 2 is definitely wonky. It is always way overboard in its readings. The Band 1 was actually more accurate in its "estimate", which I'm guessing was determined by placing the recorded track line on top of existing topographic data and reading the resulting data. I've found other altimeters in the past to also be prone to inaccuracies, and sensitive to weather conditions. Altimeters do best at least a certain height over sea level (~400 feet or so, depending on pressure conditions), and day/night changes (pressure drops at nightfall) and heavy winds (lots of little microchanges in pressure) both affect the altimeter reading. Honestly, MS would do best to drop the reliance on barometer readings for altitude, and go back to the old way of reading existing map-based topographic data. Or, allow us to manually input elevation readings at certain known spots, to help calibrate the altimeter as we go. Long story short, reading altitude from barometric pressure is hard, and requires some intelligent massaging of the data to get accurate readings.
