And as a bonus, a breakdown of each 100m segment for both guys' final lap in the 4 finals:
Doha 2019:
Jakob 54.55 (13.89-13.62-13.43-13.61)
Kerr 55.13 (13.88-13.50-13.76-13.99)
Tokyo 2021
Jakob 54.4 (13.6-13.7-13.5-13.6)
Kerr 54.1-54.2 (13.5-13.5-13.5-13.65ish)
(The race analysis only list splits down to the tenth of a second, and since Kerr's time end with .05 it's hard to know if I should round up or down)
Eugene 2022
Jakob 55.24 (14.05-13.85-13.56-13.78)
Kerr 56.00 (14.21-13.70-13.84-14.25)
Budapest 2023
Kerr 53.4ish (13.6ish-13.25-12.93-13.62)
Jakob 53.76 (13.64-13.32-12.89-13.91)
(The race analysis lists Kerr's last lap as 52.77 but that is inaccurate, as he was right behind Jakob at the 1100m mark)
