CS2

Opening win %Z

After this player’s opening kill, how often their side still wins the round.

Formula

Among rounds where this player scored the opening kill:

win_pct = (rounds_won_by_opener_side / openings) × 100

We also track how many openings and wins fed the rate.

Inputs

Field Meaning
Opening kill First kill of the round credited to this player
Round winner Which side won the round

Minimum sample

Hidden until the player has at least 3 opening kills. Below that, the rate swings too easily to show.

Where you’ll see it

  • Player card Duels slide
  • Match expand roster derived column when exposed

The UI shows the percentage with a sample label, e.g. 62% (8 openings).
