> The /fitness page and other places that display form can now show it as a percentage of fitness instead of an absolute number. This makes the form zones (optimal training etc.) more applicable to athletes with less than 100 fitness. This setting is available in “Options” on the fitness page and in /settings. “Percentage of fitness” is the default setting for new athletes.
