POP Series 5
Thanks to the presence of two Gold Stars, Espeon and Umbreon, in the set, POP Series 5 is a lot more popular than the other POP Series, and there are more videos of pack openings on Youtube than for the other ones. The 5 uncommons and 6 commons appear to be printed on a single sheet just like in the earlier set; a model with each uncommon appearing 4 times on the sheet (leaving the other 101 positions for the commons) still fits the observed data very well.
A rare in every 10 packs still looks like a good estimate for the moment, although it may be a bit on the low side; I may end up revising it slightly (to 1 in 8) after looking at all 9 POP Series - unlike the main sets, I am looking at these only as I get to them. The big question is whether the Gold Stars are rarer than the other rares. Based on the data from 364 packs, they may be - or they may not be. Here are the rare pulls I observed:
For the moment I will go for a model where all rares have the same rarity (except for one printed 21 times on the sheet). Thus, the rarity table is identical to that for POP Series 4:
