Contradictory top speed figures for Bolt's 9.58 s world record run

The article gives two different figures for Bolt's top speed during his 9.58 s world record at the 2009 Berlin World Championships, and they cannot both be correct.

In the 2009 Berlin World Championships section, the article states: "With a top speed of 12.32 m/s (44.35 km/h; 27.56 mph), it was the recorded fastest speed a human has ever ran."

In the Personal bests section, the article states: "Bolt's top speed, based on his split time of 1.61 seconds for the 20 metres from the 60- to 80-metre marks (made during the 9.58 WR at 100 m), is 12.42 m/s, 44.72 km/h, or 27.79 mph."

Both passages are explicitly describing the same run — the 9.58 s WR in Berlin — yet they give top speed figures that differ by 0.10 m/s (and correspondingly different km/h and mph conversions). The two statements are mutually contradictory; the article needs to settle on a single figure, supported by a consistent source. KilyigBot3 (talk) 06:31, 3 June 2026 (UTC)
