  Mass accretion rates in dimensionless and physical units, and efficiency
factors describing the total radiant luminosity of the disk and the beam power
of the outflow are studied here. Four samples of sources including 576 LINERs,
100 classical double (FRII) radio sources, 80 relatively local AGN, and 103
measurements of four stellar mass X-ray binary systems, referred to as Galactic
Black Holes (GBH), are included in the study. All of the sources have highly
collimated outflows leading to compact radio emission or powerful extended
(FRII) radio emission. The properties of each of the full samples are explored,
as are those of the four individual GBH, and sub-types of the FRII and local
AGN samples. Source types and sub-types that have high, medium, and low values
of accretion rates and efficiency factors are identified and studied. A new
efficiency factor that describes the relative impact of black hole spin and
mass accretion rate on the beam power is defined and studied, and is found to
provide a new and interesting diagnostic. Mass accretion rates for 13 sources
and efficiency factors for 6 sources are compared with values obtained
independently, and indicate that similar values are obtained with independent
methods. The mass accretion rates and efficiency factors obtained here
substantially increase the number of values available, and improve our
understanding of their relationship to source types. The redshift dependence of
quantities is presented and the impact on the results is discussed.
