CS2 utility analysis: flashes, smokes and grenade damage

Grenade effects describe a different part of a match from kills and deaths. Read their units and samples before deciding what they imply about support work.

What does utility analysis measure?

JumpThrow records flash assists from kill events, blindness caused to enemies and teammates, and health-capped HE or fire damage. It also counts grenade throws. Caused and received effects are separate: taking friendly damage does not establish who caused it.

Enemy blind time sums recorded blindness in seconds. Repeated blind events can involve the same opponent, and a high total does not prove that teammates were able to act on every flash.

For HE and fire, read enemy damage beside throws and friendly damage. A per-throw rate answers a different question from total damage. No throws provide no attempt denominator; a missing historical value is different from a recorded zero.

What does Utility Rating mean?

Utility Rating v1 is a score from 0 to 100 based on quantity and benchmark-adjusted quality. Flash, HE and fire throws contribute scored effects; smoke contributes usage. It is not a percentile, a universal skill rank or proof of round-winning impact.

Round-based rates use the player’s recorded participation in the selected scope, including overtime and partial participation. Team grenades per round divide summed throws by summed player-rounds. Missing side participation can make those rates unavailable.

Can the numbers explain a lost round?

A low flash-assist count alongside many throws is a reason to inspect relevant fights. It does not settle whether the cause was timing, target choice, lack of contact or something else. The Utility view holds aggregate records, without grenade positions, throw timings or round sequences.

Use available 2D replay to inspect a sequence and duels to read openings and trade support. Site control supplies planted-round outcomes. Treat those views as evidence you can compare, with their own limits.

What about smokes and unused grenades?

Smoke throws measure usage. Through-smoke kills do not attribute ownership or effectiveness to a particular smoke. A smoke that delayed a push may have no damage or assist receipt here.

Unused-utility value is an estimate based on purchases, pickups, estimated teammate drops and usage. It cannot establish exactly which grenades a player held at death. Check the available record before describing an item as wasted.
