I'd guess that it is in the low one cent range. Why do you think it would be less than that? I'd guess the airline miles are around one cent and that SPG is probably a bit more. Otherwise SPG would probably lose a bunch to those who transfer points.
Most cashback cards are 1% so I am betting that in a competitive market those issuing miles are also spending in the 1% area.
