Compared at the same moment
Cars are compared on the race clock: same track, same temperature, same traffic.

Post-race Analytics
Find out where the race was won or lost, in seconds you can check.
Post-race Analytics reads the official sector times of the NLS and the 24h Nürburgring and compares your car with any car in the field at the same moment of the race. Add the AiM or VBOX files of your car, and it measures the neutralisations on your car and compares your drivers corner by corner.

01 · Overview
See your whole race on one screen.
The overview shows the best lap, the theoretical best, the clean average, the finish in the class and overall, the gap to the class best lap and the stints and stops. The lap-time trace puts every lap next to the class median and shades the laps where the whole class was slowed down.
The lap chart shows the position of every car lap by lap, in the class or overall, starting from the qualifying grid when you add the qualifying to the event.
- Lap-time trace against the class median, with slow zones shaded
- Stints band coloured by the pace rank of the driver
- Lap chart from the grid, with positions gained or lost per stint
- Race and qualifying of one event with one switch
02 · Where the race was lost
Split the gap to the class winner into parts that add up.
Post-race Analytics splits the total gap to the class winner, or to second place when you won, into pace, pit stops and racecraft. The three parts add up exactly to the gap.
The numbers behind each part are shown underneath: the average clean laps of both cars, every pit stop with its lap and standing time, and the time each car spent above its own average pace.
- Pace, pit stops and racecraft in seconds
- Every stop with its lap and official standing time
- Laps down counted at your own median lap
03 · Class and pit stops
Benchmark every pit stop in the class.
The class view ranks every car on its best-lap deficit to the fastest car and benchmarks the pit stops of the whole class: number of stops, official standing time from the pit-in to the pit-out line, average per stop and the difference to the best total in the class.
Smart stops marks the stops made during a Code 60 or slow zone, when a stop costs the least. The final standings show the best time of every car in every sector.
- Official standing time per car
- Difference to the best pit total in the class
- Smart stops during Code 60 and slow zones
- Final standings with the best sectors of every car
04 · Sectors and FocusIndex
See where the lap time is lost out of proportion.
The best sectors of your car are set against the class best. The FocusIndex divides the loss in each sector by the loss you would expect from that sector's share of the lap: above 1.0 the car loses more than it should, so that is where to work first.
Per driver, Sector focus turns the same analysis into a list with a priority for every sector: high, medium, low or on pace.
- Best sector of the car with the driver who set it
- FocusIndex per sector, with the three focus sectors first
- A priority per driver and sector
05 · A vs B on the race clock
Compare any two cars at the same moment of the race.
Every lap and sector gets its time of day from the line crossing, so A vs B compares two cars at the same moment: the same track, the same temperature and the same traffic. The gap chart shows the real gap after every lap and, per lap, whether the time went in clean running, in a neutralisation or in a pit stop.
Where we lost time splits the gap into pace per sector, pit stops, neutralisations and the rest, and the sector table compares every clean sector with the rival's passage closest in time.
- Gap per lap, coloured clean, neutralised or pit stop
- Pace per sector, pit stops, neutralisations and rest, adding up exactly
- The three sectors with the biggest losses, with the lap where it happened
- Code 60 and double-yellow sectors detected from the field
06 · Strategy
See why another strategy worked better, in seconds.
The strategy comparison shows the stops, the official standing time, the pit-lane time and the total pit loss of your car and the selected rivals, with the laps per stint and per driver, and the stints of every car on the race clock.
Per rival Stint9 measures the effects in seconds: pace on clean sectors, standing time, pit lane and the time lost in Code 60 and yellow zones, which also covers stopping during a neutralisation.
- Stops, standing time, pit lane and total pit loss per car
- Stints of every selected car on the race clock
- Measured effects per rival in seconds
07 · Matchups
See which driver met which rival on track, and who was quicker.
Who drove when shows one lane per car with a block per driver. The matchup table lists every pair of your driver and a rival driver who were on track together for at least five minutes, with the typical clean lap of both and the difference per lap.
Close on track marks the pairs that crossed the line within five seconds of each other. One click opens the sector detail of that window.
- Who drove when, for your car and the selected rivals
- Every driver pairing on track together for five minutes or more
- Difference per lap on clean sectors only
08 · Drivers
Compare your drivers fairly, even when they never share the track.
Your drivers never drive at the same time, so each clean sector is compared with the median of the other class cars in the same ten minutes. Conditions cancel out, and the lowest number is the fastest driver for the conditions.
Driver stats puts the best lap, the top-three average, the theoretical best and the clean average of every driver side by side, and Sector focus gives every driver a priority per sector.
- Pace against the class at the same moment, in seconds per lap
- Sector bars per driver
- Driver stats and the best sector of every driver
- Every lap of the car with stint, driver and sectors
09 · Car data · AiM and VBOX
See per corner where a driver loses time.
With the AiM or VBOX files of your car, Stint9 compares your drivers corner by corner, but only on clean passages: no Code 60, yellow flag, traffic or pit-lane sector, so a slow lap behind a yellow never counts against a driver. Corners are found automatically and named from OpenStreetMap.
Patterns show what a driver does differently across all corners, the track map shows where the gap grows, and the corner table gives the brake point, minimum speed, throttle and exit speed per corner. The same logger data measures Code 60 and slow zones on your own car, per 100 metres.
Real data of a VDS Motorsport car at an NLS race; driver names anonymised.
- Gap per lap, typical lap and theoretical best per driver
- Patterns: earlier braking, less minimum speed, later full throttle, slower exit
- Where to work and what went well, per corner
- Code 60 and slow zones measured on your own car
- AiM .xrk and .xrz, VBOX .vbo, analysed in your browser
How Post-race Analytics measures
A race engineer can check every number.
Every figure comes from the official timing or from your own logger, and every split adds up to the gap it explains.
Neutralisations taken out
Code 60 and yellow sectors never count as pace; with logger data they are measured on your own car.
Parts that add up exactly
Pace, pit stops, neutralisations and the rest add up to the total gap.
Pit stops on the official lines
In NLS 6 the measured stops matched the organiser's stand times within half a second for 88 of 99 cars (checked 3 Aug 2026).
Works together
The tools share their data.
