Blood separation systems and methods draw whole blood from a blood donor selected from a population of blood donors. The whole blood of the selected blood donor has a known hematocrit value that varies within the population of blood donors according to morphology of the selected blood donor. The systems and methods operate a pump in the inlet line to convey a volume of whole blood from the donor at a commanded flow rate for processing into plasma constituent and concentrated red blood cells. The systems and methods set the commanded flow rate to vary the volume of whole blood conveyed over time as a function of the known hematocrit value of the selected donor. The systems and methods obtain, after processing the whole blood volume, a targeted volume of concentrated red blood cells, which is substantially constant for the population of blood donors despite variances in known hematocrit values among the donors.
