I thought I made this pretty clear in my first post. We observe the Hubble "constant" as an input parameter.

However, big bang models explain the observed distance red-shift relation pretty well, and can interpolate a distance from a red-shift or vice versa reliably. This includes the region where z=6, which is definitely non-linear compared to the local environment. So to that end:

It agrees perfectly, because it IS the observed one. The expanding universe cosmologies have their parameters tuned to match this observation.
