Could be true but I noticed that if you keep your jewels at max then the S rank mystery boxes spawn rate decrease by a lot or maybe is my bad luck but I compared it doing several episode 1 runs and when I dont have all the jewels most of the time I got at least 1 S-rank MBox or sometimes 2 of them, but if I keep 3 jewels then I have like 2 - 4 runs without any S-rank Mbox (I use adventurer cookie so I got 4 - 5 Mystery Boxes in each run).
