There is no shortcut on airflow tuning: the Passage 4 rewards preparation and punishes improvisation.
Seasonality interacts with airflow tuning more than most forecasts allow for, so a rolling review beats an annual one.
Why airflow tuning matters on the Passage 4
Restricted airflow suits mouth to lung customers moving from traditional products.
Documentation is not paperwork for its own sake; on airflow tuning it is the difference between a clean clearance and a delayed one.
