19 sec / 660 sec = 2.9% duty cycle
19234046 uS / 38222 injections = 503 uS / injection
At idle the focus generates a 3mS pulse every 172mS. 1.7% duty cycle.
Reading this thread I would assume that your car uses "peak and hold" injectors. Maybe the "peak" part of the injection cycle is being measured while the "hold" is not?
