Standard rates merge every base slot for a species and are shown per time window: morning 04:00-09:59, day 10:00-19:59, night 20:00-03:59. Swarm, radio-broadcast, and Headbutt tables keep their own labeled rows, and every row carries HG/SS markers.

Trainers

Teams are the exact source party records. Moves and held items appear only when the trainer format defines them. Reward = last party member level × 4 × trainer-class multiplier; double battles double the base payout where the engine applies it.
