"Educated Guess" values have been recorded from Corecraft test server which isn't a primary source (credit for that research goes to NiM and Shiro). However, when I've tried to verify some of their values now and in the past, they've come out pretty much right and in my opinion are preferable to any guessed values and can be used for the time being until primary sources are studied.
It should be noted that Coilfang/Hellfire instance values were recorded with less rigour, such listing damage values as they appeared on Corecraft instead of looking at actual ability behaviour from WDB (and then adjusting it if there's evidence of nerfs) so don't copy them blindly.
