There are scoring criteria somewhere on this site:

http://www.thecwsa.org

There are 2 main "circuits" plus Supras inclusion of the Pro Men in the PWT. There is the Endless Wave Tour and the World Series of Wake
Surfing. Some INT leagues are starting to expand to include wakesurfing as well.

Most events are run under the CWSA umbrella, but each event coordinator has latitude for their event. Some use cumulative scoring, some use day 1 scores to seed for day 2 (or 3) and only the final run counts.
