Ability Value Added

ABVVALv0.1.0 · baseline · validated 2026-07-16

Computed. The pipeline computes this metric and its values are ranked.

What it measures

Round-rate value of utility that affects enemies, measured in enemy-seconds under an effect and netted against the time it costs the caster's own team.

Formal definition

Per round played: 0.35 × enemy-seconds under an effect − 0.15 × teammate-seconds under an effect, where enemy-seconds are effect duration × enemies affected, summed over the player's ability casts. Weights are versioned constants published here. On the inputs VALORANT sources currently supply only the first term can be evaluated — the canonical ability payload records enemies affected and effect duration and nothing else — so in practice the published number is 0.35 × enemy-seconds per round. Every cast is weighted alike; ultimates are not scored differently.

Inputs

  • ability events with affected counts and effect durations

Exclusions

None beyond the standard confidence floor.

Sample & population

100 rounds

Unit
value/round

Percentile interpretation

Initiators/controllers naturally rank higher; use agent-adjusted view.

Confidence = source confidence × model confidence. Values from baseline models are capped at 0.7. Below-minimum samples display the value grayed out with no percentile.

Example

A flash catching two defenders for 1.2s each is 2.4 enemy-seconds → +0.84 for the round.

Known limitations

  • Information value of recon is approximated by affected counts and durations in v0
  • Ability damage is not a term: the canonical ability payload has no damage field and no registered source supplies one, so a damage term would be an input we do not have
  • The teammate-cost term is defined but inert: no source records how long an ability held a teammate, so friendly-fire utility is currently unpunished
  • An ultimate counts the same as a basic cast of equal reach, which understates ultimates and overstates cheap area utility
  • Requires replay/recording-derived ability events; official API does not expose per-cast effects for pro matches
