Nature Matching Methodology
See how Favorite Pokémon turns base-stat profiles into transparent Nature matches, including the data used, scoring stages, variety rules, and model limitations.

How a score is built
Walk the five steps from base stats to a published Profile Fit and Match Tier.
1. Base Stats
Start from the Pokémon’s six base stats. Nature matching never derives competitive EV spreads; it reads the raw profile the species brings into battle-stat calculations.
Interactive score breakdown
Three columns connect the Pokémon profile, the Nature preference, and qualitative score contributions that explain the published Profile Fit.

How Forms and Varieties Are Scored
V1 rules decide whether a form is scored on its own stats, reuses the default variety, or is not listed separately on match boards.
Example
Deoxys — Attack Forme
Scored separately
Its base-stat profile differs substantially from the default variety, so it is scored separately.
Default
Attack Forme
Base-stat profile diverges — this form is scored separately.
The published dataset currently focuses on default varieties. Expanding battle-relevant form rows is versioned separately.
Model scope
V1 is intentionally narrow so scores stay explainable from base-stat profiles alone.
What V1 Uses
- Species base stats (six stats)
- Nature raised and lowered stats
- Derived profile fields: attack bias, physical share, speed class, bulk class, importances
- Published Profile Fit score, Match Tier, reason codes, and profile focus
What V1 Does Not Use
- Movesets, abilities, and held items
- Team composition, competitive formats, and usage statistics
- IV/EV investment as part of the published match score
- Pokémon GO mechanics (main-series Natures do not apply there)
These boundaries keep the model reproducible and independent of specific competitive formats.
Neutral Natures
Five Natures leave every non-HP stat unchanged.
Hardy, Docile, Serious, Bashful, and Quirky are labeled Neutral Effect. Their Profile Fit score is null—they do not appear on Strong or Good match boards, and the methodology UI never invents a midpoint score for them.

Data sources
Pokémon species, varieties, types, base stats, and Nature effects come from structured Pokémon data. Variety scoring rules, profile labels, score thresholds, and explanatory text are maintained by Favorite Pokémon as versioned algorithm and editorial data.

Match Tier is derived from Profile Fit with versioned thresholds (Strong ≥85, Good ≥70, Situational ≥50). Internal dataset id remains 0.1-seed for reproducibility.

Methodology FAQ
Does a higher Profile Fit mean the Nature is competitively best?
No. Profile Fit measures base-stat alignment only. Moves, abilities, formats, items, and usage data are not included.
What does the breakdown represent?
It shows the exact input profile and published reason codes used to explain the result. Contribution labels are evidence levels—not additive production weights.
How are Match Tiers assigned?
Match Tier is derived from the rounded Profile Fit with versioned thresholds: Strong ≥85, Good ≥70, Situational ≥50, otherwise Conflicting. Neutral Natures are Neutral Effect with no score.
How are forms and varieties handled?
V1 independently scores default varieties and battle-relevant forms with distinct base stats. Cosmetic-only forms reuse the default result and are not listed as duplicate match entries. Remaining eligible form rows are added in versioned dataset updates.
What about neutral Natures?
Neutral Natures have no raised/lowered stats. They are labeled Neutral Effect with a null score—never a fabricated midpoint.
Why does Gengar’s Modest fit sit behind Timid?
Gengar’s V1 profile prioritizes Speed slightly above Special Attack. Timid raises Speed and typically ranks #1 (Strong ~98), while Modest remains a Strong alternative (91).
