Stats
Stats on this page
- PO Points - Playoff points
- ASP - Average starting position
- AFP - Average finish position
- ARP - Average running position
- Succ% - Success rate - The percentage of races in which the driver has finished better than their expected finish based on starting position (see PFAE). We use the expected finish instead of starting position (which, I think if you asked the driver, they'd say is what they're trying to beat) because using starting position punishes drivers who qualify well: it would be impossible to succeed when starting first, for example.
- Fin. - Races finished
- SS - Speed score - 1000 x the ratio of the driver's 95th percentile lap to the race 95th percentile lap. A good read of a driver's top speed. [Read more]
