1227730 $A1 Idle Fuel Table

I'm working with a Fireo engine transplant, 3.4 V6 using DIS, 1227730 ECM $A1 definition.

Below are the idle fuel table parameters. It seems like the MPH Above Which can become Idle Fuel is incorrect? It seems to me it would be MPH BELOW Which can become Idle Fuel would be correct.

The $A1 data log I'm working on with Excel to filter Idle Fuel data, the BLM average for Idle Fuel is 154. The vehicle has a horrible stalling problem, perhaps 154 Idle Fuel BLM is a clue to the stalling?
