Idle Tuning - Airflow: Idle Base PN Airflow

OK, so once again I went out and got us some data from a completely warmed up engine.

So here we see that according to the Idle Base PN Airflow channel we should be flowing 42 lb/hr (this number of course comes from the Idle Airflow table we discussed above) however our PCM is only asking for 40 lb/h as per the Idle Desired Airflow channel. So we are 2 pounds off?
