FIELD NOTES / TOPIC

Lap timing

Understand lap identity, comparison eligibility, progress, and timing units. Keep the session context attached to every lap before building a comparison or leaderboard.

A practical reading path

Read the guides below with a specific interface in mind: the event you need to identify, the measurement you need to explain, and the result state your audience should see. Treat each article’s proposed application model as a starting point, then confirm the selected provider’s actual contract.

Use the fictional sample explorer to connect these ideas to a concrete response. The data-model reference explains the shared fields; sport-specific extensions remain deliberately small. No live subscription or production data access is implied.
