Great Idea - some issues to fix
Ive used Alpine Replay to measure my stats during a week-long holiday with friends. Sometimes we got to high top speeds (80 kph for an intermediate skier) and sometimes to low ones (7 kph for a regular slope). Slope time and rest time also seems not to be too well calculated. The concept of tracking your stats is very interesting, though.
