KV is StatVault's single-number player value metric. It is the AV-equivalent layer: one proprietary season total for every player, cumulative career value across seasons, and era-aware cross-sport comparison.
Volume output vs position peers
Per-opportunity performance
Games played / season durability
Era + team quality adjustment
High-leverage contribution
Knox Value (KV)is StatVault's proprietary player value layer. Unlike traditional AV (Approximate Value), KV uses direct individual measurement rather than team-stat allocation, applies position-specific scoring formulas for all 4 major sports, incorporates per-opportunity efficiency alongside volume, and normalizes across eras using z-scores within season-position cohorts.
Career KV = cumulative sum of all qualified season marks. Peak KV = mean of top-5 seasons. Era-Normalized KV = career sum adjusted for era inflation/deflation.
