I remember seeing auto magazines quote 0-100k as 0.1 slower than 0-60 (or 0-60 as 0.1 faster than the 0-100k) without testing both, and was always skeptical of that as a rule, especially with the 1ft rollout games. But I guess by the time you're at ~60mph an extra 2mph/3kph is probably right around 0.1s.
And your own run shows 0.56s from 90-100kmh, so the last 3kph taking 0.1-0.2 tracks.
