Where the data comes from
- Your matchmaking gamesLive
Connect your match history in Settings and we pull in your Premier, Competitive and Wingman demos automatically. Every match gives stats for all ten players.
- Demos you uploadLive
Got a demo from a scrim or a match we missed? Drop it in and you get the full round-by-round breakdown.
- SteamLive
Names, avatars and profile links. Steam doesn't share match history on its own, which is why we use demos.
- FACEITLive
Match history and Elo for players with a FACEIT account.
How we keep it honest
- No data means a “—”, never a made-up zero.
- Every stat tells you how many matches or rounds it's based on, so you know when a sample is small.
- Rating charts only show ratings we actually saw. We don't fill in the gaps.
- When you compare players, everyone gets the same time range and the same formulas.
- The RoundCtrl Rating is an open formula, shown below. It isn't HLTV's or Leetify's rating.
What the stats mean
- RoundCtrl Rating Rating
- Your overall impact in one number. 1.00 is about average, and anything above is a good game. Built from kills, deaths, assists, KAST and damage. The full formula is on the About page.
- K/D ratio K/D
- Kills divided by deaths.
- Win rate Win%
- How many of your matches you won. Draws don't count as wins.
- Headshot % HS%
- How many of your kills were headshots.
- Average damage per round ADR
- How much damage you deal per round. Overkill damage doesn't count, so a 1-HP enemy is worth 1.
- KAST KAST
- How many rounds you made a difference in: you got a Kill, an Assist, Survived, or got Traded.
- Opening duel success Open%
- How often you win the first fight of the round when you're in it.
- Clutch success Clutch%
- How often you win the round when you're the last one alive on your team.
- Utility damage / round UD/R
- Damage from your HE grenades and molotovs, per round.
- Enemies flashed / round EF/R
- How many enemies your flashbangs blind per round.
- Flash assists / match FA/M
- Kills your teammates get on enemies you flashed, per match.
- Trade kill % Trade%
- How often your kills avenge a teammate who just died (within 5 seconds).
The RoundCtrl Rating formula
It's the community's well-known approximation of HLTV Rating 2.0, using per-round averages (KPR = kills per round, and so on):
Impact = 2.13·KPR + 0.42·APR − 0.41 Rating = 0.0073·KAST% + 0.3591·KPR − 0.5329·DPR + 0.2372·Impact + 0.0032·ADR + 0.1587
A few details
- Warmup doesn't count.
- A trade is a kill on someone who killed your teammate in the last 5 seconds.
- “Enemies flashed” only counts enemies blinded for more than 1 second. Team flashes don't count.
- Team damage and team kills don't count toward your stats.
- A clutch starts when you're the last one alive on your team, and you win it if your team takes the round.
