But the last time I saw figures on this, the redshift from the most distant objects indicated a velocity of about 70% of lightspeed.

Well, no, the highest redshift objects that have been found have a z of around 6.3, which is better than 96% of lightspeed. Furthermore, these objects are seen well after the decoupling time (that is, the time when atoms formed and the universe became transparent), so there's a considerable temporal "lever arm" (as I describe in my "geek alert" above). An object at the decoupling time (the physical limit of how far back we can see) would have a z of around 1000.
