You fill in the actual airflow at each table temperature, and the PCM calculates (interpolates) the airflow for temperature values between the table points. For example, the PCM will calculate the airflow at 73*, 82*, 97*, 113*, 129*, etc., based on knowing the accurate airflow at 68*, 104*, and 140*.
