Regularity
The core principle of the discipline: not speed counts, but consistency and precision.
Regularity describes the core principle of the discipline of the same name: it is not the highest speed that counts, but the ability to maintain set times and average speeds as precisely as possible. A regularity rally rewards consistency and teamwork rather than speed. This is exactly what makes the discipline accessible to beginners, since neither a racing licence nor a high-performance car is required.
