The logs are mostly useless for drawing any comparison because of how bad the testing session was
-Blizzard did the test, just to do the test and check bosses off a list. Very few raid groups had a full 20 people inside.
-A lot of players didn't even have the Artifact Weapon equipped
-Even if players had their Artifact Weapon, there was no common number of traits, so some people had 20 while others had 1
-The usual ilvl scaling shennanigans- where using a ilvl 700 ring with a socket is better than an 850 ring because they'll both be scaled, but the socket stays, and where some trinkets go nuts
