According to my calculations, this should be near 0.5 mm/s.
You need a very big scale.

Try again. What do you think a millennium is? A parsec? The prefix
mega-?

1 Mpc/ka = 978 Gm/s, or about 3262 times the speed of light. He's got
bigger problems than you thought.

In other words, even one parsec (without the prefix) per millenium is
nearly 1 Mm/s (978 km/s). Thus 1 microparsec per millennium is equal
to a meter per second, within the precision many of you accept with
knots and the like.
