Hubble Velocity

According to what I've been taught, the distance-related redshift seen by Edwin Hubble is an artifact of an expanding Universe. That is, as light travels through space, space itself expands, redshifting the light (matter is embedded in space and does not itself expand but is instead carried along like raisins in a rising loaf of bread).

Ok. So assuming a mostly constant Universe expansion rate R, this means that the real velocity of a galaxy moving away from us would always be just R. However, the perceived velocity would always be H0D.

Is this correct so far, that is, should the Hubble Velocity be seen as perceived, not actual? Thanks!
