Fitness, Form and Fatigue doesn't take into account manually added items
The values of fitness form and fatigue do not update for manually added items. I realize this may be due in part because of lack of details/heart rate data. I do think they could do something about this though, for example, when on work travel, I try to do enough to maintain or come close to maintaining my fitness, I have no way of accounting for this since manually added workouts basically do nothing.
Additionally, weight lifting and strength training do not impact the fatigue, fitness and form scores. I believe this is a significant oversight for users who are attempting to leverage Strava's capabilities to aid in their workouts and fitness routine. As a summit member I'd really like to have some way of introducing this to our scores even if it's a "rough" estimate of efforts.
