Experimental farm evidence ranks eligible fresh charts without promising a particular PP return.

Mania Farm uses a research signal informed by sampled player top plays, accuracy, performance, map structure, and exposure-adjusted adoption. It aims to recognize efficient charts while accounting for evidence quality.

.farm selects the highest-index eligible fresh charts first in the checked implementation. Strong strict matches precede the more permissive fallback. A chart still needs to satisfy the room's hard filters and key mode.

Farm availability depends on staff enablement and validated data. The 4K and 7K research models have different coverage; their raw index values are not interchangeable. The farm index is an experimental ranking signal, not a guaranteed amount of PP for your score.

Variety can use bounded farm-aware weighting while retaining all eligible structural styles. Missing evidence is not an automatic exclusion from Variety. See selection rules and release history.

When enabled, .farm prefers the strongest eligible fresh index candidates before weaker-feature fallback. .variety broadens the structural selection.

Farm is not a structural pattern. Confidence, evidence coverage, and key-mode models matter; raw 4K and 7K indices are not interchangeable.
