Match the final’s lane assignments, then collect breaststroke race data. Every level has its own Read Me. Mastery scoring requires 80% to unlock the next level. You can practice any drill while its reference measurements are being reviewed.
The original 30 fps recording changes camera views. The arena screen may lag the pool view. Record video timestamps as observations; do not label them official electronic splits.
Use metres and seconds throughout. Unknown or obscured observations remain blank. Coach-reviewed references determine which checkpoints are scored.
