Rider markers are estimated from published lap and sector times, then interpolated between timing gates along the known course centreline. They do not represent exact racing lines, braking points, speed traces or GPS telemetry.
Comparisons use a normalized simultaneous lap start. They combine historical runs from different races and years; the on-map order is a virtual comparison, not an actual race result.
