    "data": {
        "note": "SWOLF (swim + golf) scores stroke efficiency for one length = the strokes taken plus the seconds taken. Like golf, lower is better: gliding further per stroke or swimming faster both cut the score. A 25 m length in 18 strokes and 30 s is a SWOLF of 48. Compare like with like — it is pool-length and stroke dependent — so the score is normalized to 25 m here; chase a lower SWOLF at the same speed to swim more efficiently, not just harder.",
