While correct in how the MAF picks up, 4k RPM's isnt a set in stone point as it depends on where PE (power enrichment) is set to come online at. The MAF scale though does rely on the EQ Ratio to determine the commanded A/F and then uses the airflow data the MAF gives it to determine what EQ Ratio to use.
