Is the dual point system staged?

Well, in RX-7's, there are two primary injectors that work from 0-3800RPM, and over 3800 the primary injector duty is cut in half and two secondary injectors come online to split the difference. That is staged fuel injection, and is very unusual for piston engine cars.
If DPFI computers run one injector up to a certain RPM, then cut in half bringing the second online to take up the other half... that would suprise me. Anyone know the flow rate of DPFI injectors?
