Using the 'hiking' activity when performing my skydive activity (still need to create my own to get all info) I noticed that my heart rate as measured by my Venu2s is suddenly very high and not according my real heart rate. When doing the actual freefall, it's showing fairly correct numbers, but when climbing (sitting in the plane, performing no real activity) it is higher that it should be. What ca be the cause of this? (again, it is NOT reflecting my real heart rate, measured with my hand in neck)
