It’s hard to give ‘good’ values for fitness, fatigue and form as they are very much context dependent. For example, triathletes training in 3 disciplines tend to have higher values of fitness than single sport athletes as a result of managing training load across three disciplines as opposed to only 1 or 2. But that doesn’t necessarily mean that a triathlete is more ‘fit’ than a runner. Additionally, the higher the level of athlete, the higher the training status or fitness level we tend to see generally, although there are many elite athletes that manage successful performances with much lower levels of fitness (i.e., they train less and this works better for them). These fitness, fatigue and form values help guide us, but due to various factors, they should never be taken as gospel.
