Power Ranking

Power ranking describes how well the entity (driver, constructor, engine) performs all things being equal. For example, a driver in a slow constructor can still have a high power ranking if they constantly out-perform their team-mate and the car.
Power ranking changes based on the Qualifying Power Index values the entity scores in their qualifying. The algorithm for power ranking changes works in the following way:
- See how much each feature affects the QPI. The values have been discovered experimentally.
- For each feature, calculate the QPI a generic entity would be expected to receive. The difference between this and the actual QPI is the effect of the entity
- Compare the effect of entity to the existing power ranking, and adjust the power ranking towards the effect of entity.
The goal of the algorithm is to change the entity's power ranking enough so that it reacts to changes, but not too much so it stays consistent despite fluctuations in success.
