The Bloodmallet SimC based datasets show Venthry for example, being significantly further ahead of any other Covanent.
(set max renown 35)
Venthyr soulbinds: 6,400 - 6,500 dps
Night Fae: 5,800 - 6,000 dps
The item sets are listed that are used for bloodmallet, when these items are copied to the AMR simulation, so the items are identical, there is a substantial different in the values calculated when using the Venthyr Soulbinds.

Considering they are both patchwerk fights, I’m not sure why these are so drastically different, even if AMR tries to add in player error rather then mathmatically perfect sims - this seems like far too large a difference. I’ve adjusted the fight length on the AMR simulation as I can’t seem to find the SimC/Bloodmallet fight length, but this does not appear to make a significant different in the DPS values.
