 On a kayak series, I don't follow a bunch of it. I have seen it. I believe they accumulate a length of fish throughout the day is how they do it. On a boat in a five-fish limit or a traditional bass fishing tournament, you would have your best five or best three of the day, or you would do a catch, weigh, and release type deal. They do a catch, measure, and release, and they accumulate length there.
