Nobody can know but I‘m pretty sure they didn‘t change anything. Start tracking your chests and you get a feeling for outliers. And
you should get about one a week
Those statements are the reason for complaints and stuff. People start expecting a chest once a week when they start skipping. But thats just wrong and a rough estimation that never has to happen.
Track your chests yourself and you will get a feeling for how often it occurs.
Thats my tracking:
April 1/10/25 Mai 2/8/12/18/21 June 1/10/18
No decrease to be seen…
