The 18g (thanks, Dr. Michael):

Put those on top of each other and it could be the same car on two different dyno runs.

Applying logic:
18g-XT will outflow 18g
therefore 18g-XT 8cm2 will outflow HTA68 10cm2

And that pretty much sums up the top-end debate.

(As if it was ever really a question, the HTA68 is more like a 16g-XT and probably should be compared to a 16g-XT, not an 18g-XT.)
