Perfect Order (ME03) SIR reportedly 1.23% per English booster, about 1 in 81

English boosters of Perfect Order (ME03) reportedly pull a Special Illustration Rare 1.23% of the time, about 1 in 81, so chasing one is a long shot. The figure is attributed to a TCGplayer study of more than 3,500 English boosters, in publications dated April 3, 2026. Mega Hyper Rare is reportedly 0.06%, about 1 in 1,667, though publications vary on that ratio (Godpack reports 1 in 1,786, UltraBall about 1 in 1,670). Other published per-booster figures are 20.97% for any Double Rare, 11.20% for any Illustration Rare and 8.54% for any Ultra Rare. The comparison publications (Cardlytics, Godpack, UltraBall) mainly point back to the same TCGplayer study, so they are not independent studies. These are observations from English boosters, not official rates and not certified French rates; no large independent French sample was identified. Six SIR cards share the category, including Meowth ex (Miaouss-ex) 121/088 and Mega Zygarde ex (Méga-Zygarde-ex) 120/088. Splitting 1.23% evenly gives about 1 in 488 for one specific SIR, a calculation assuming equal distribution, not a measured rate. The Mega Hyper Rare version of Mega Zygarde ex, numbered 124/088, belongs to a different rarity category than the SIRs. Assuming independent boosters, the calculated chance of at least one SIR is 1.2% for 1 booster, 3.6% for 3, 7.2% for 6, 10.5% for 9, 20.0% for 18 and 36.0% for 36. For one specific SIR, assuming six equally likely cards, it is 0.2% for 1 booster, 0.6% for 3, 1.2% for 6, 1.8% for 9, 3.6% for 18 and 7.1% for 36. A French retailer's catalogue lists blister, tripack (three boosters), Elite Trainer Box (nine boosters plus accessories) and display (36 boosters) formats, but no source established a better per-booster rate for any French product format.
