100m, 200m, 100m hurdles, 110m hurdles
These four track events are wind-affected. Tailwind above +2.0 m/s makes the mark wind-aided. The 400m and longer races are not affected by wind for record purposes.
Wind matters in track and field. A tailwind helps a sprinter; a headwind slows them. To keep records honest, World Athletics caps the legal tailwind at +2.0 m/s for sprints (100m, 200m, 100mH, 110mH) and the horizontal jumps (long jump, triple jump). Marks with more tailwind count for the meet but not for records or qualifying.

Both horizontal jumps are wind-affected. Same +2.0 m/s rule. Each attempt has its own wind reading.
In decathlon and heptathlon, the wind average across all wind-affected events must be at or below +2.0 m/s for the score to be record-legal. Individual marks can be over.
Wind helps the time but not the technique. AI form check grades your form independent of the wind reading, so you know whether the PR was real or just lucky weather.
