I was looking for the formula to calculate each arena's amount of cards in chests. Each arena has a "base weight" W (20, 27, 34, 40, 46, 52, 58, 64, 70, 76, 82, 88) and amount of cards in chests are based on them. Prior to the June update, amount of cards in crown chests was W, now it's 0.8W rounded to the nearest integer, or int(0.8W+0.5). For boosted crown chests, since the arena 12 version contains 141 cards, it can be observed that doubling comes before rounding.

Maybe the pixelcrux calculator didn't use this type of formula to calculate the number of cards, instead they're input individually?
