the English card pool and modeled collation are shared. Loose-pack EV
appears inside each box calculator and is never published separately.

How the estimate works
English market inputs
Every valued card and sealed-product identity comes from the exact English TCGplayer group.

Standard OP, extra booster, and premium booster products use separate disclosed rarity recipes.
Filters follow the draw
The complete no-chase box is drawn first. Sift changes counted value afterward and never rerolls or backfills.
