Undaunted
We have now reached the final countdown of the last three sets of the vintage era. The box ratios for Undaunted are similar to those for Unleashed, but as explained in my introductory post on the HeartGold & SoulSilver series, I estimate the ratio of Pokémon LEGEND to be reduced from 3 per box to 2.5 per box. The rarity table looks as follows:
The raw data for the holos, rares, Pokémon LEGEND and Pokémon Prime looks as follows (dashed lines indicating where the transition from H13 to H12, etc., would occur):
I see no indication of artificial rarity differences. As to the reverses, I looked at a small sub-sample (see below):
With 80 different reverses in the set, two possible sheet compositions would be to print either all 26 unsommons as well as 15 commons twice (model 1), or all 29 commons and 12 uncommons twice (model 2). However, neither model fits the observed data, so it looks to me like the RE2 cards are some other kind of mixture of reverse commons and reverse uncommons. As to the fact I observed vary few reverse rare holos, I would simply attribute that to the small sample size.
Edit 2023/8/8: Corrected the rarity table (old version incorrectly still had 6 Pokémon Prime per box instead of 5).
Edit 2023/09/09: Changed sheet size of Pokémon Prime to 10x11 (see introductory post on HeartGold & SoulSilver Series above)
Edit 2023/11/19: Changed sheet size of Pokémon Prime in model to 10x10 (see introductory post)
