just found the answer to your question on your linked site, about three lines below the quote you used:

"Here the extra factor a(ti) / a(t0) accounts for the expansion between the end of inflation Ti ~ 10¹⁵ GeV and today, T0 ~ 10^-4 eV."

IOW, most of the "scale change" that they are talking about takes place AFTER the inflation stops, that is to say, it occurs through the normal non-inflationary expansion of the universe, as I opined in my previous reply.

So the universe is still expanding, right? only now it is either at or below the speed of light? Correct?

Sorry about "you didn't read the link". I read your post and then clicked on the reply button. I took a fair amount of time in forming the reply and didn't see this intervening message, however my answer still applies, barring the "you didn't..." part.
