Rating

This is a proprietary match rating developed by whiskeyo. It uses the same live scoreboard as the rest of the analyzer — kills, ADR, KAST, and so on — through the current playhead. Knife rounds are left out.

The scale starts at 1.00 and has no ceiling. A typical game lands around 5.25; a historic demo can print 10+.

Ranges

A typical line sits at 5.25, with a designed spread of about 1.70. The curve is that expected distribution; the dashed line is the typical game at the center. Use the bands as a reading guide, not hard cutoffs.

How it is calculated

Each box-score rate is turned into a standardized score $z = \frac{x - mean}{std}$ . Four pillars mix those $z$ values, then:

rating = \max (1.00, round (5.25 + 2.10 \times z_{total}, 2))

There is a floor at 1.00 and no ceiling, so a historic demo can print 10+. A line that sits on every reference mean is 5.25.

KAST is the 0–100 percentage already shown on the board. rounds is at least 1 so a tick before the first freeze stays defined. Clutch terms are wins, not attempts. A 5-kill round is an ace.

Inputs

Symbol	Board field	Notes
`R`	Rounds	Competitive rounds started by this tick
`K`, `D`	Kills, deaths
`ADR`	ADR	Enemy HP damage / `R`
`KAST`	KAST	0–100
`FK`, `FD`	First kills, first deaths	Opening duel of the round
`2K`…`5K`	Multikills	`5K` = aces
`TG`, `TW`	Trades (got / was)	5-second teammate trade window
`UD`	Utility damage	HE / molotov / inferno, same ADR cap
`FA`	Flash assists
`C1`…`C5`	Clutch 1v1–1v5	Wins
`P`, `Def`	Plants, defuses	Completed

1. Firepower (45%)

\begin{array}{rcl} z_{kd} & = & \frac{KPR - DPR}{0.30}, where KPR = \frac{K}{R}, DPR = \frac{D}{R} \\ z_{adr} & = & \frac{ADR - 75}{18} \\ z_{firepower} & = & 0.6 \times z_{kd} + 0.4 \times z_{adr} \end{array}

2. Impact (25%)

\begin{array}{rcl} z_{entry} & = & \frac{\frac{FK - FD}{R}}{0.12} \\ mk & = & \frac{1 \times 2K + 2.5 \times 3K + 5 \times 4K + 8 \times 5K}{R} \\ z_{multi} & = & \frac{mk - 0.25}{0.20} \\ z_{impact} & = & 0.5 \times z_{entry} + 0.5 \times z_{multi} \end{array}

3. Support (18%)

\begin{array}{rcl} z_{kast} & = & \frac{KAST - 70}{12} \\ trade & = & \frac{TG + TW}{\max (K + D, 1)} \\ z_{trades} & = & \frac{trade - 0.35}{0.15} \\ util & = & \frac{UDPR}{10} + \frac{FA}{R}, where UDPR = \frac{UD}{R} \\ z_{util} & = & \frac{util - 0.70}{0.40} \\ z_{support} & = & 0.5 \times z_{kast} + 0.3 \times z_{trades} + 0.2 \times z_{util} \end{array}

4. Clutch and objective (12%)

\begin{array}{rcl} clutch & = & \frac{1 \times C1 + 2 \times C2 + 3.5 \times C3 + 5.5 \times C4 + 8 \times C5}{R} \\ z_{clutch} & = & \frac{clutch}{0.06} \\ obj & = & \frac{0.8 \times P + 1.2 \times Def}{R} \\ z_{obj} & = & \frac{obj - 0.10}{0.10} \\ z_{clutch_obj} & = & 0.7 \times z_{clutch} + 0.3 \times z_{obj} \end{array}

$z_{clutch}$ has mean 0 (no subtraction). Plants weigh less than defuses.

Combined score

\begin{array}{rcl} z_{total} & = & 0.45 \times z_{firepower} + 0.25 \times z_{impact} + 0.18 \times z_{support} + 0.12 \times z_{clutch_obj} \\ rating & = & \max (1.00, round (5.25 + 2.10 \times z_{total}, 2)) \end{array}

The player detail pane shows the four pillar $z$ values next to rating. Half-up rounding to two decimals, then the floor.

Reference means

These mean / std values are the “typical game” the z-scores are built around. They are not live match averages.

Rate	Mean	Std
`KPR − DPR`	0	0.30
`ADR`	75	18
`(FK − FD) / R`	0	0.12
`mk`	0.25	0.20
`KAST`	70	12
`trade`	0.35	0.15
`util`	0.70	0.40
`clutch`	0	0.06
`obj`	0.10	0.10

Worked example

20 rounds, 10–10, ADR 75, KAST 70%, five 2Ks, 4 trades got / 3 was, 140 utility damage, one plant and one defuse, no opening duels or clutch wins:

\begin{array}{rcl} z_{firepower} = z_{impact} = z_{support} = z_{clutch_obj} & = & 0 \\ z_{total} & = & 0 \\ rating & = & 5.25 \end{array}

That is the center of the scale on purpose.
