Big green number = guaranteed hundo. 15/15/15 produces the single highest possible catch CP, so if the encounter shows exactly this, it's 100% — no appraisal needed. Keep it.
Band = the 96–99% window. It's only ~15 CP wide. A catch landing in here is near-perfect, but a high-attack ~93% can occasionally sneak into the range, so confirm with a ★★★★ appraisal before deciding it's a keeper.
Two columns: read L20 normally and the L25 boosted column only when the listed weather is live. Boosted catches also arrive higher-level, so they cost less dust to max — prefer keeping those.
Shadow attack/defense modifiers don't change the stored CP, so Shadow, Primal-raid, and normal catches of one species all share the same numbers. Computed from base stats × level CPM; validated against published Kyogre and Tauros hundo values.
