As of now, the average is about 1 light year/year.
Explanation:
From the age-approximation as A ( tentatively 13.8 ) billion years
for the radial expansion A billion light years, the average rate is 1
light year / year.
If this is so, then the rate, just after Big Bang instant, could have
been very much faster than the speed of light, to reach the current
average of 1 light year/ year.
I could imagine that the reader's eyebrows are raised.
Indeed, our universe is mysterious. It is impossible to be affirmative
on any scientific surmise on the history of our universe, as a Holistic
Whole.
