Do you think the scientists who study the expansion of the Universe don't or wouldn't include this kind of detail?

Can you please let me know how you would be able to determine that? Currently we have a hard time just figuring out how far something is away from us. I believe we use the red-shift ( + brightness??? ) from standard candles. I am not sure if we would be able to determine the ones that are not receeding from us as they would be a very few scattered throughout all of the galaxies that we can see as they get farther away it would be even more difficult I would think.
