Ability Value Added
ABVVALv0.1.0 · baseline · validated 2026-07-16Computed. 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
- Minimum sample
- 100 rounds
- Baseline population
- Players in the same game/window; agent-adjusted split available
- Direction
- higher better
- 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
