These categories are made up of event groups. There are 5 event groups: 50's, 100's, 200's stroke, 200 to 1500 frees, and IM's. At least one swim must be completed from each event group that makes up the category. An overall score will be calculated that automatically works out the highest scoring swim in each event group and adds them together for a total score. For example, if you swim two of the events in the Sprint group, the computer system will work out which one scores more points and add it into the overall score with your best scores from the other event groups. The events vary depending on age and whether the meet is Long Course Meters or Short Course Meters.
