Sadly, not figures available for public consumption.

If the figures are off, and 8jc variance really is of little consequence, then what makes the rest of the data from the same testbeds any more trustworthy?

Scenarios may have improved since then. Things may well be different now as opposed to even testbed items produced 18 months ago. Not enough public data to safely make the assumption either for or against, and that is the biggest issue. Faith alone is not enough for some.
