Definitions
Best theoretical lap time: the sum of the best sectors in a session, or group of sessions. The best theoretical lap time is always less than or equal to the best lap time.
Best X laps average: the average of the best X laps, where X can be any integer greater than or equal to 1. In general we use best 20 laps if a sufficient number of laps has been completed in the session. This number can give a more accurate indication of the pace of a car/driver than looking at only the best lap time.
Driving time: the total driving time for each driver, not including the time spent in the pits. This is how most race series calculate driving time.
Sanitized average lap time: the average lap time for a stint, calculated according to the following algorithm:
- Start with all laps for a stint
- Remove all safety car laps
- Remove all in and out laps
- Calculate the average of the remaining laps
- Remove all laps a certain threshold above the average (we use 10% by default)
- Recalculate the sanitized average using the remaining laps
Graph explanations
Raising average
The raising average graph can be used to analyse practice/qualifying sessions or a race. The graph is a plot of the average best X laps for different values of X, starting from 1. Therefore, at any point, X, the corresponding y-value shows the average lap time of the best X laps. Aside from the advantage of comparing average lap times over best lap times, the raising average graph also gives an indication of the consistency of each car/driver. The shallower the slope the more consistent a car/driver is over the corresponding number of laps shown on the x-axis.
The raising average plot is useful to see the overall performance of a car/driver in a session, but does not allow for analysis of individual stints or contiguous subsets of laps.
Gap graph
The gap graph is only used to analyse a race and shows the gap between a reference car and other cars in the field. On the y-axis the gap to the reference car is shown in seconds, and on the x-axis the lap number of the race is shown. The reference car is marked by the horizontal line at y = 0 [seconds]. Positive y-values indicate that a car is behind the reference car, and negative y-values indicate that a car is ahead of the reference car.
The gap chart is useful for analysing the pace of the reference car over periods of laps (e.g. stints and/or the whole race) relative to the other cars shown on plot. Because a number of laps are studied there is a filtering effect that gives a much clearer picture of the relative pace of the two cars compared with looking at raw lap time data.
To compare the pace between two cars, the slopes of the lines are studied. A negative slope indicates that the reference car is losing time relative to a specific car, and a positive slope indicates that the reference car is gaining time relative to a specific car. The magnitude of the slope gives the pace difference between the cars with the units [seconds/lap].
Stint graph
Stint graphs are used to analyse the performance of a car over each stint throughout a race. Each horizontal line on the graph represents a single stint. Along the x-axis is the lap number of the race, so the point in the race at which each stint occurred can be clearly seen, as well as the duration (number of laps) of each stint, which is shown by the length of each horizontal line.
