Raider io is good enough data.
Just a reminder, in case it’s relevant, that for some time, I think it was changed in BFA, raider IO wasn’t logging every run.
I can’t recall the exact circumstance, but there was a limit to the number of runs, something like 500 per dungeon, where anything that fell below the key level and completion time of existing runs, it simply wasn’t logged.
I have no idea if that’s important, but if we’re comparing old data it’s possible that there are numbers that are no longer available via r. io and could potentially skew comparisons. Probably doesn’t affect anything, but I felt compelled to mention it.
This still exists. Towards the end of the week the API stops recording the lower runs. Its in their FAQ if you want to go read about the specifics of it.
