Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that black hole masses are determined by observing the orbital dynamics of surrounding matter?

Yes. Black hole masses are standardly determined by analyzing the orbital dynamics and kinematics of surrounding matter such as stars and gas.
