Do some activities earn more points than others?

Yes. We have grouped our activities into three groups. The activities we have deemed to require a high level of physical exertion will be rewarded on the basis of 3 points per minute. The activities deemed to require a medium effort of physical exertion will be rewarded on the bases on 2 points per minute. The activities deemed to require a low level of physical exertion will be rewarded on the basis of 1 point per minute.
