Whole trainers in bold, the raw estimator in brackets — 2.04 means two trainers is right on the line and three is comfortable.
Six of the best counter
Every trainer brings six copies of the single best counter — the theoretical floor.

How this is worked out
The boss is ranked once at level 40 with rankCached (the same memoised call /raids makes), then the three bands — rank 1, ranks 1-6, ranks 13-24 — are re-simulated at each attacker level with an 8-run Monte Carlo each. Holding the party fixed and moving only its level is deliberate: it answers "what if my party were level 20" rather than "what would a level-20 player's completely different party be", and it is about ten times cheaper than re-ranking every attacker seven times. The Estimator itself is Pokebattler's definition, time to win including rejoin time divided by the raid timer.
