@masmica: Yes, the plausibility filters work only if a track has been recorded via GPS.
@rené: The problem with skiing tours is that you just cannot estimate the calorie consumption when going downhill. It totally depends on the snow and the difficulty of the tour. It can be between 30% and 300% of an estimated standard value. It would make sense if everyone would use heart rate sensors, but this is not the case.
i have read that so far you just added sports for which you know calorie consumption. are there any plans to expand the group of activity rate influencing sports? i would really appreciate... for me it is a pity that skiing tours is not included.
For the activity ratings, we tried to select standard sports for which we know the calorie consumption values. The list of standard sports can be found below the activity levels on the users' hompages.
Beside the fact that ordinary walking doesn't effect the activity level, there should be a system one can see how many km or kcal or whatever somebody needs to reach the next level. Motivation is the main force for activity.
