Perfect in what year? I don’t think we can use the word perfect either. Perfect would be the speed of light (or faster, depending on whether you want Einstein climbing out of his grave to get you). Bolt could probably have had 9.55 with a +2.0m/s and no celebration.
Slightly under 2m/s tailwind and no celebration, Bolt was at the 9.55 except for his RT.
