Is a booster box of CORE worth opening?
On average, no: selling the cards from a CORE box would get you $48.36, 17% of the $279 it costs. A typical box gives $43.54 and only 0.0% of boxes get your money back. If you're after a specific card, buying it as a single is usually cheaper.
How reliable the rates are: good (several sources that agree).
CORE pull rates

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.
2010-2015 core booster: 8 commons and 1 rare per pack, with a foil in some packs. Konami ratios: Super 1 in 5 packs, Ultra 1 in 12, Secret 1 in 23 and Ghost 1 in 288. Ultimate Rares have no published rate: they don't count.
