Those measures aren't detected on 1 day but weeks (except pero gambit, but thanks to stamina i was seeing a lot of results on last and extra stages). It still be a small part of data to detect a potential "pattern", so i prefer to use the other (and realistic) term, trends.

And trends can change over time. However, in Gacha if we simplify the elements to type of cards we got a nice scheme to find a good chance hunting R cards. Remember that N gacha always have (at least) 1 R card, we are lucky to see this condition, which is not present in GHQ or stages.

EDIT: Finally a 2;6 in event.
