According to description on Garmin site Hill Score is calculated when I record a running, walking or hiking activity. Despite the fact that I record daily walking activity during last months Hill Score is not calculated yet. It shows that 4-week elevation gain is 1338 meters, but still not enough data to calculate Hill Score. Maybe I miss something? On my way I have uphill segments with a grade of more than 2%, but maybe there is also a minimal length for every such kind of uphill segment? I use MARQ2 Aviator with the latest 15.76 firmware.
