How records work here
Each entry is the fastest legal time ever recorded for that event in the loaded data — across every ISL Championship PDF we've parsed. Records carrying multiple seasons of daylight get a Standing chip; records set this season get New. ISL is the ultimate authority on the official book — we display what the published results show.
