As mentioned: until logs come out, some trinket assumptions might be off. But starting today I am hoping to be able to dig through the log data. That frond is at the TOP of my list, so stay tuned.
Also, Re: BIS. Actually, you can do "BiS" on AMR, it's just a bit of a moving target. It's built to address this WF/Socket problem in the following way:
1. Set your filters right (you can get BiS for any gear you are willing to get, for example, you can exclude a mythic raid. Or you can exclude top level crafted gear if it's too expensive. Or, you can set warforged/socket levels to none, or +5, etc).
2. Import your bag data (use the addon when you load your character).
3. Mr. Robot then finds all of the gear available to you, based on your filters. Let's say you include everything except set WF/Socket to none. Then, he also takes into account all of the gear you own. So if you DO get a lucky item, that is taken into account when calculating your BiS.
So it's sort of a moving target, that adjusts to the gear you own. And as mentioned, it's still theoretical in that it's based on the assumption you set the tool too, including the type of fight, filters, etc etc etc.
