Where do I lose time?

One line from start to finish.

The delta is your time minus the reference time at the same metre of the lap. The line climbs where you lose and falls where you gain.

A delta per sector

Each sector time gets its delta under it. In AMS2 the sector bounds come from your sector times.

Sector 2 of lap 19: +0.929 s

The Ghost

The reference car drives next to yours. It is where the reference was after the same lap time, so the gap on track is real.

What did the faster lap do?

Both lines and both speeds, metre by metre.

Zoom into a corner and you see where each car drove and how fast it went. Lap 24 was back on the throttle at 2,155 m and kept 102 km/h through the second part of the chicane. Lap 19 lifted again.

Two racing lines

The lines come from the world positions that the game sends. You see how far apart they ran and where they cross.

Roggia: 2.67 m apart at 2,230 m

Every chart, both laps

Speed, pedals, gears and steering show both laps. Move over the map, and the cursor moves in each chart.

Slowest point: 85 against 91 km/h

Corner chips

On a track with mapped corners, a corner that costs or gains 0.015 s or more shows its delta in a red or green chip.

The chip takes the place of the corner number

Which lap do I compare against?

Only laps that make a fair comparison.

The list shows laps on the same game, track and layout, in the same car class. Your own laps come first, then your friends. A lap that cannot be a reference is counted, with the reason.
