I’ve read the related threads about historical %s dropping slightly over a short period, and I have a vague idea on how it works. But this log has steadily dropped from 98 to 85 over the past 3.5 weeks, and shows no sign of stopping. Looking at other players’ W1 logs, I can’t find any exhibiting the same behavior. I have to think there’s a bug here.
edit: I did find the same issue on some other logs from the 22nd/23rd. From what I’ve ead on the forums, it’s normal not to lock historical percentages in during the first few days, but it seems like they just never got locked in at all?
