AeroPod gradient measurement

Post by ted.kelly »

The garmin IQ data field for AeroPod shows gradient to 0.1 %.
How is this measured?
Is it a direct measure of the inclination of gravity with respect to the AeroPod?
Is it derived from the velocity (from the paired wheel sensor) and changes in the barometer reading?
Is it some sort of filtered combination of those two approaches?
