Stakeholder availability vs Project personnel availability

HoRaBa p. 110: Stakeholder map
HoRaBa p. 43-44: P.1 Time constraints

Implies that on the Stakeholder map, it shouldn't be 1-100, but related to some hourly number? A Stakeholder is a category, while project members are individuals.

So the stakeholder map number is the normative value against which project members are to live up to? Fall short and raise a notification that the Quadrant value may be wrong?
