Relative distances and speed

If most matter(maybe superclusters) have been separating at
an ever faster rate for 13+ billion years, what is the minimum
percent of the speed of light the furthest group is now
traveling relative to our speed? How does this relate to the
initial inflation speed? Have there been slow downs? Or, how
close were clusters when they were first formed? I am looking
for absolute distances w/o gravitational distortion. Thank you.
