In the early years, the dressage phase was fairly inconsequential in determining the final standings. It was quite possible for a horse to have a terrible dressage test, then run a clean cross-country and show jumping, and still finish near the top of the standings. Since then, correct dressage training has become increasingly important should a horse and rider wish to be placed (complete all sections and finish in the top 12). This can be traced back to Sheila Willcox, who took a particular interest in dressage, becoming abundantly clear when she won Badminton three years running in the 1950s. She had a strong influence on Mary King and Lucinda Green amongst others.
