Is a booster box of CORI worth opening?
Yes, on average it pays off: selling the cards from a CORI box would get you $85.01, more than the $83.47 it costs. But that's an average: a typical box gives $71.10 and only 41% of boxes get your money back.
How reliable the rates are: fair (community estimate).
CORI pull rates
How many cards of each rarity group come in a 24-pack box, how many packs it takes to pull one specific card of the group and how much the group adds to the box value.

Where the numbers come from
The expected value adds up, for each rarity group, the copies in a box times the average price of its cards (the English card, with its TCGplayer price or, if there isn't one, Cardmarket's converted). The simulation opens 10,000 boxes with the same rates.
2026 core booster, with extended-art Ultra and Starlight Rares. 9-card pack: 8 commons and 1 foil (a Super Rare or, in its place, an Ultra or Secret Rare), no rares. Per 24-pack box, 18 Super, 4 Ultra and 2 Secret Rares on average: Konami's official 2015 ratio, which the community treats as still current; Konami hasn't restated it. Starlight and extended-art Ultra: about 3 of each per 12-box case (TCGplayer); a count of 13 Beyond the Brave boxes agrees.
