Technical Analysis Metrics

Smurf Indicators

The app analyzes up to 1,000 matches for the opponent's current race to calculate a Smurf Score. Each metric contributes to the score. Note: Most metrics require at least 10 relevant matches to be active; otherwise, they contribute a neutral 0.25 points. "Fast games" are defined as matches lasting less than 60 seconds.

  • MMR Delta: The gap between Career Peak MMR and Current MMR.
    • 0 pts: ≤ 300 (Normal variance)
    • 0.5 pts: 301 - 499 (Suspicious gap)
    • 1.0 pt: ≥ 500 (Significant rank tanking)
  • W/L Ratio (Fast Games): Compares instant wins to instant leaves (under 60s).
    • 0 pts: ≥ 0.95 (Opponent leaves as often as the player)
    • 0.5 pts: 0.76 - 0.94
    • 1.0 pt: ≤ 0.75 (Opponent leaves significantly more often than the player)
  • Duration Ratio: Average Win Duration divided by Average Loss Duration.
    • 0 pts: ≤ 1.3 (Balanced lengths)
    • 0.5 pts: 1.31 - 1.69
    • 1.0 pt: ≥ 1.7 (Wins are long, but losses are very fast)
  • Smurf Losses (%): The percentage of total losses that occurred in under 60 seconds.
    • 0 pts: < 10%
    • 0.5 pts: 10% - 17.5%
    • 1.0 pt: > 17.5% (High frequency of intentional leaves)
  • Mirror Loss %: Loss rate in same-race matches (e.g., ZvZ).
    • 0 pts: ≤ 60%
    • 0.5 pts: 61% - 69%
    • 1.0 pt: ≥ 70% (Indicates dodging specific matchups)
  • Account Maturity: Total 1v1 career games. Smurfs often use fresh accounts to obfuscate their history.
    • 0 pts: Mature account (≥ 750 games)
    • 0.5 pts: Under 750 games
    • 1.0 pt: Below 500 games (Highly suspicious)
  • Unranked Preference: Percentage of matches played in Unranked mode.
    • 0 pts: ≤ 20% (Standard ladder play)
    • 0.5 pts: 21% - 39%
    • 1.0 pt: ≥ 40% (Intentional avoidance of ranked match-making)
  • Random Preference: Percentage of all recent matches played as Random.
    • 0 pts: ≤ 20% (Standard race selection)
    • 0.5 pts: 21% - 39%
    • 1.0 pt: ≥ 40% (Frequent random play)
Smurf Barometer Results

The total score from the indicators above determines the classification shown on the profile (Max: 8.0):

  • No Smurf: Score < 3.0
  • Possible Smurf: Score 3.0 - 3.99
  • Likely Smurf: Score 4.0 - 4.99
  • Definitely Smurf: Score ≥ 5.0
Case Studies

Example A: The Regular Player

This player plays through their matches and is at their natural skill level.

  • MMR Delta: 120 (Peak 4500, Current 4380) → 0 pts
  • W/L Ratio: 1.0 (2 fast wins, 2 fast losses) → 0 pts
  • Duration Ratio: 1.1 (Wins: 11m, Losses: 10m) → 0 pts
  • Smurf Loss %: 2% (1 fast loss out of 50 losses) → 0 pts
  • Mirror Loss %: 52% (Standard win/loss rate) → 0 pts
  • Account Maturity: 5,200 games (Mature account) → 0 pts
  • Unranked Preference: 5% (Standard ladder play) → 0 pts
  • Random Preference: 10% (Standard race selection) → 0 pts
  • Result: 0.0 (No Smurf)

Example B: The Smurf

This player intentionally leaves games to stay in a lower league and avoids mirror matches.

  • MMR Delta: 650 (Peak 5200, Current 4550) → 1.0 pt
  • W/L Ratio: 0.15 (3 fast wins, 20 fast losses) → 1.0 pt
  • Duration Ratio: 2.5 (Wins: 10m, Losses: 4m) → 1.0 pt
  • Smurf Loss %: 30% (Early leaves are a huge chunk of losses) → 1.0 pt
  • Mirror Loss %: 85% (Leaves almost every mirror match immediately) → 1.0 pt
  • Account Maturity: 45 games (New account) → 1.0 pt
  • Unranked Preference: 65% (Heavy unranked play) → 1.0 pt
  • Random Preference: 70% (Frequent random play) → 1.0 pt
  • Result: 8.0 (Definitely Smurf)
