I am still curious about the testing done by redditor Arfirst:
I can replicate the SP, non-dedi and dedi tests, but it wouldn't help in comparing the numbers to official where I believe there's no floating damage text to gather the data. Also there is no way I could do this on official and I don't know anyone who plays it, and of course it's shutting down soon. But if official should match dedi servers, as per invisibleqc's statements, then how can the hard-coded nerfs not show in these results?
I may have to test it myself anyway to see if the numbers really reflect Arfirst's conclusion. If I get the same results, is it possible all unofficial/dedi/non-dedi/SP is nerfed and official bosses really are almost 10x harder than anywhere else?
