CS2 Stats Explained — ADR, KAST, Rating

Why CS2 Stats Matter for Betting

Statistical analysis is the backbone of informed CS2 betting. While match outcome predictions require holistic analysis (team form, map pools, context), individual player and team statistics provide the quantitative foundation. This guide explains every key metric used in professional CS2 and how to apply them to betting decisions.

HLTV Rating 2.0 — The Gold Standard

HLTV Rating 2.0 is the most widely used player performance metric in CS2 esports. It produces a single number that represents overall player impact:

• 1.00 — average performance
• 1.10+ — strong, consistent player
• 1.20+ — elite, star player level
• 1.30+ — exceptional (only the very best maintain this over time)
• Below 0.90 — underperforming

What HLTV Rating Factors In

• Kills per round (KPR)
• Survived rounds per round (SPR)
• Average damage per round (ADR) — with a diminishing returns formula
• Multi-kill bonus — getting 3K, 4K, 5K rounds adds extra weight
• Opening kill success — first kills in rounds carry significant weight

How to Use Rating for Betting

Compare the average team ratings (sum of 5 players' ratings). A team with a higher average rating typically has more individual firepower. But be cautious: rating is context-dependent. A player might have a 1.15 rating against weak opponents but 0.95 against top-5 teams. Always check "rating vs top 10" or "rating at big events" filters on our stats page.

ADR — Average Damage per Round

ADR measures the average damage a player deals per round, regardless of kills. It's considered more consistent than K/D ratio because it captures contribution even when a player doesn't secure the kill.

• Below 70 ADR — low impact, support/utility focused
• 70-80 ADR — average for a professional player
• 80-90 ADR — high impact, entry fragger or star player
• 90+ ADR — elite damage output, among the best in the world

Betting application: ADR is the best stat for player prop bets (over/under on damage). Players with consistent high ADR are safer "over" picks. ADR is also more stable than kills across different maps and opponents.

KAST% — Kills, Assists, Survived, Traded

KAST measures the percentage of rounds where a player had positive impact through one of four actions:

• Kill — got at least one kill in the round
• Assist — assisted a teammate's kill (damage or flash assist)
• Survived — was alive at round end (on winning side)
• Traded — was killed but a teammate got a return kill within 5 seconds

KAST above 70% indicates a highly consistent player. Below 60% suggests the player frequently has "zero impact" rounds.

Betting application: KAST is the best predictor of consistent team contribution. A team of 5 players with 70%+ KAST will be more consistent (fewer blowout losses) than a team relying on one star player with 80% KAST and four players below 65%.

K/D Ratio — Kills per Death

The simplest stat: total kills divided by total deaths.

• Above 1.20 — significantly outperforming opponents
• 1.00-1.20 — solid, positive contribution
• Below 1.00 — dying more than killing (not necessarily bad for support roles)

K/D is intuitive but context-dependent. Entry fraggers (players who lead site takes) naturally have lower K/D because they face the hardest duels. An entry fragger with 0.95 K/D but high opening kill success rate is more valuable than their K/D suggests.

Opening Duel Stats

Opening kills and opening deaths measure performance in the first engagement of each round:

• Opening Kill Rating — percentage of first duels won. Above 55% is strong for an entry fragger.
• First Kill / First Death ratio — entry fraggers should have a positive ratio. If a player gets first-killed more than first-killing, they're losing crucial opening duels.

Betting application: Teams with strong opening duel players tend to win more pistol rounds and gain early-round advantages. This correlates with strong T-side performance.

Headshot Percentage

The percentage of kills secured with headshots. High headshot percentage indicates strong aim:

• 40-50% — average for professionals
• 50-60% — strong, aim-focused player
• 60%+ — exceptional (usually rifle/pistol specialists)

Note: AWP (sniper) players typically have lower headshot percentages because the AWP kills with body shots. Don't compare AWP players' HS% with riflers.

Clutch Statistics

Clutch stats measure performance in 1vX situations (player is last alive against multiple enemies):

• Clutch win rate — percentage of 1vX situations won. Above 15% for 1v2+ situations is strong.
• Clutch rounds won — total number of clutch rounds. This correlates with experience and composure.

Betting application: Teams with clutch-capable players salvage more lost rounds. In close matches (likely to go overtime), clutch ability becomes a deciding factor.

Impact Rating

Impact rating measures high-value contributions: multi-kills, opening kills and clutch rounds. While overall rating weighs consistency, impact rating highlights the "big play" factor.

A player with 1.05 rating but 1.15 impact creates more advantageous situations than their rating suggests. Conversely, a player with 1.15 rating but 0.95 impact might be "stat padding" by getting low-value kills.

Putting It All Together for Betting

1. Team comparison: Sum of average team ratings → the better team on paper. But check recent form (last 3 months, not career).
2. Star player dependency: If one player has 1.25 rating and the rest are below 1.00, the team is volatile. Bet against in accumulator-safe spots.
3. Map-specific stats: Always filter by map. A player with 1.10 overall but 0.85 on Nuke will be a liability on that map.
4. Opponent tier: Stats against top-10 teams are more predictive than overall stats. A player farming lower-ranked opponents inflates their numbers.
5. Recency: Last 3 months of stats are more relevant than 12-month averages. Form is temporary, and team dynamics shift with meta changes.
