pub fn enemy_power_derived(chapter: i64) -> Option<f64>Expand description
The derived-mode curve G(ch)/(ρ̂(ch)·z(ch)), or None when the
calibration tables are not baked — callers fall back to legacy. ρ̂ is the
zone-corrected pressure target and z the zone difficulty correction; their
product is the raw-scalar pressure the curve implements.
