Race length
We consider around 6-10 minutes (using reference times) to be a good baseline for race length.
Preferrably we want longer races, but we also want to avoid a high number of laps.
The values will be adjusted as we race more on the tracks and get a better feel of them.
Check out the table below for the different multipliers for each race length.

Length	Multiplier
Quick	0.5
Baseline	1
Short	1.35
Medium	3
Long	6
Very long	10.5

We use math.ceil(baseline_laps * multiplier) in the code when calculating the number of laps.

Starting time
All starting time options have the same likelihood of being selected by default. However, by selecting early or late, the starting times from the first or last half of the list will be six times more likely to be chosen, except for Midday, where Noon, Afternoon, and Late Afternoon are 12 times more likely to be selected.

Check out environment data for details about the different starting times.

Time scale
The chances for the different time scales to be picked are: x1=6.67% x2=17.78%, x4=26.67%, x12=44.44%, x24=4.44%.

Weather
All weather options have the same likelihood of being selected by default.
However, the following options changes the likelihood of the different weather types being selected:

Dry:The only possible weathers are Clear, Mostly clear, Partly cloudy, Cloudy and Looming clouds.
Clear:Clear, Mostly clear, Partly cloudy, Cloudy, Looming clouds has a 3.5x higher chance of being selected.
Wet:Overcast wet, Drizzle, Light rain, Moderate rain, Heavy rain, Thunderstorm and Rainstorm has a 3.5x higher chance of being selected.
Extreme: The only possible weathers are Moderate rain, Heavy rain, Thunderstorm and Rainstorm.

Check out environment data for details about the different weather types.

Starting track rubber level
The starting track rubber level is a value between 10-40 (low), 18-60 (medium), 25-70 (high), and 50-100 (very high), with lower values having a higher chance of being selected.
If random is selected, the value is a number between 0-100.

Race start type
The standing start type has a 4 times higher chance of being selected than the rolling start type.

Grid ordering
In the grid ordering, PI has a 1.5x higher chance of being selected than random.
If the grid ordering is based on PI, descending is 2.5x as likely to be selected as ascending.

Reference times
Reference times are based on track times recorded by a stock 2017 Nissan GT-R (R35) equipped with street tires and a Performance Index (PI) of 702.
Check out the setup to see the exact settings or track times for different cars to see a comparision between different cars on Circuit de Spa-Francorchamps.
