====== Experimental Mania Farm ====== Experimental farm evidence ranks eligible fresh charts without promising a particular PP return. ^ Availability | Mania 4K and 7K; staff enablement and validated evidence | ^ Documentation status | Current behavior | ^ Behavior reference | v6.6.16 ยท reviewed 2026-09-28 | 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. [[commands:farm|.farm]] selects the highest-index eligible fresh charts first in the checked implementation. Strong strict matches precede the more permissive [[wiki:style_fallback|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 [[wiki:map_selection|selection rules]] and [[updates:start|release history]]. ===== Worked example ===== When enabled, ''.farm'' prefers the strongest eligible fresh index candidates before weaker-feature fallback. ''.variety'' broadens the structural selection. ===== Limitations ===== Farm is not a structural pattern. Confidence, evidence coverage, and key-mode models matter; raw 4K and 7K indices are not interchangeable. ===== Related articles ===== See [[wiki:pattern_atlas|a related guide]] and [[wiki:start|all features]].
