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