This is a very strange result, because it really does not align with my experience in actually SHOOTING these rounds. I still have my 10" 243win barrel, but I'd have to do some thinking on figure out how to run a 60kpsi test with a 10" 6 ARC (anyone have a 10" Savage 6 ARC barrel I can borrow?) - it would be easy to get a 10" 6 ARC AR barrel, but the pressure standard won't be the same. I don't really have interest in spending $500 just for this test (I'd run H4350 and Leverevolution, but between RL16 and CFE223, the results would be nearly identical, certainly analogous).Here is the same comparison with Reloader 16 and CFE223 which were #3 on both lists.

In 25yrs shooting specialty pistols, not just running QL simulations, I have NEVER been able to replicate velocity of a larger cartridge with a smaller one. I had a 6 BR XP100, which is slightly larger case than a 6 ARC, and I never could match what I could get from a 243win, or now 6 creed. I was never able to match my 300 WSM with a 308win and never match 308win with 30-30 or 30 BR in specialty pistols (or 300blk SBR's). I was never able to match 223rem with 221 Fireball... Never could match 7-08 with 7-30 waters... Same deal for naysayers about 454 casull in the Alaskan, or snubnosed 44mags... We can't match 454 casull with hot 45 colts because we can't get enough powder into the case. Same for hot 44spcls vs. 44mag - the larger case always yields the higher velocity (when using the same pressure standard)... So I've walked this road several times - so this is really odd to see QL claiming parity for these two.
Naturally, it's clear the 6 creed is gaining more speed per inch, so picking 11", we have more speed on the creed, but I'd be baffled to confirm that a 10" 6 ARC can keep up with a 10" 243win in the real world.
If I could find a line on a .445" Savage bolt head (left hand) and a 10" 6 ARC barrel to borrow or buy for $100-150, I could test them side by side.
