Initialization and Accuracy

Why and how

Can Aktiia replace an ambulatory blood pressure monitor supplied by my Doctor? Does the "cuff hypertension" affect the initialization? I have high blood pressure variability. Why can I not see sudden changes In my blood pressure with Aktiia? How can I perform a new initialization before the due date? Why, after exercise, does Aktiia display high blood pressures values? Do I need to make a new initialization always at the same time of the day? How do I initialize?
