Session notes

Timing strategy

  • Capture a baseline lap first; use fastest/slowest highlights to balance pacing for teams or athletes.
  • Switch to milliseconds when measuring QA automation or animation timings, then revert to hundredths for presentation.
  • Drop the embed in Notion, Stream overlays, or operations dashboards so stakeholders can view live timing.
