Because of the 90% rule, a driver can get an official classified result even if they fail to complete the final few laps. Likewise, those who fail to complete 90% of the race don't get classified as finishers, no matter how close they come. Another important percentage-based regulation in F1 is the 107% rule. To reach that cutoff number, officials simply convert the fastest lap into seconds and multiply it by 1.07. There's also the 75% rule, which decides how championship points get distributed when a race is stopped before its scheduled distance.
