Arc (weapon) pool — model approximation
The character pool math is exact (no 50/50 in NTE, S-rank limited is guaranteed). The Arc pool, however, uses an Epitomized Path mechanic that does not map cleanly onto our 50/50 schema: in reality, the first S-rank Arc after soft pity is the featured limited 25% of the time, with Epitomized forcing a guaranteed limited by pull 80. We approximate this as 50/50 with a guarantee after a loss. The long-horizon probability (P[featured by pull 80]) converges correctly to 100%, but short-horizon featured probabilities (e.g. "P[featured in 60 pulls]") are biased high in our calculator. Treat Arc results as upper-bound estimates.
