After reviewing my recent rides I notices that the altitude data lags behind by about 9-10 seconds based on the power data - whenever there's a power spike that should start at the beginning of a climb there's 10 seconds before the climb on the altitude graph actually begins, likewise when the power drops there's about 10 seconds before the altitude stops climbing. The power and GPS track seem to be in line though. Has anyone else experienced similar issues?
(top is power, middle altitude, bottom grade)
