Base stats, IVs, EVs and natures: four different layers
Base stats describe a species/form; IVs and effort training belong to an individual; natures modify the resulting stat profile. Keep those layers separate before interpreting a stat comparison.

The baseline is not your party-screen number
Our reference tables show base stats from the cached default-form metadata. A base Speed of 100 is not an in-battle Speed of 100. Level, individual values, effort training and nature can affect the displayed result. Compare actual battle-ready values at the relevant level when deciding who moves first.
Training and inheritance are different questions
An IV describes an individual parameter; effort training describes a separate development layer. Games differ in how these can be inspected or adjusted and in which training systems exist. Do not apply a current-game item or training method to an older title simply because the terms IV and EV appear in both guides.
Use a benchmark rather than maximum everything
For advanced play, ask what a particular change accomplishes: surviving a relevant attack, acting before a particular opponent, or securing a damage threshold. The legal roster, regulation and team plan decide which benchmark matters. This page explains the vocabulary; it does not supply a current tournament spread or certify imported individuals as legal.
