After each simulated season I record the driver’s record in addition to where they finished. This lets me show their probabilities broken down by record. Early in the season I group similar records together so there won’t be pagefulls of lines. Because I pull numbers from a hat when simulating a race, this chart tends to be generous. The driver will probably need to do better to win the championship.
If they finish the season with:
    Points: Total points.
    Average: Average points per remaining races.
Chance driver will finish the season at position: Rounded percentages. As Count gets smaller there are fewer times to flush out the different possible finishing positions, so the numbers are less accurate.
Count: How many times I saw them finish the season with that many (or close to that many) total points. Notice the times I force them to win or not qualify in all their races.
