Describe the observation first
“Attempted the opening duel in 7 of 18 rifle rounds” is an observation. “Entry player” is a hypothesis. Keep these separate in the interface and in the data model.
Look for counterexamples
Map, side, economy, and team strategy can all change a player’s responsibilities. A single demo is a small sample. Show the rounds that support a label and the rounds that complicate it.
A useful report
Include opening attempts, trade opportunities, utility sequences, and late-round situations. Link each aggregate back to the underlying round. The CS2 Metrics Engine is a place to explore this approach.
