His point was quite clear, and he made it several times. Most of the top times were largely solo efforts. He feels that if some top runners were pushing each other it could lower. That is an opinion, but certainly a valid one. Most people on this board think Nelson's time on the old course was superior, adding to the validity that the current course record is a little soft.
Solo efforts makes the record 'soft'? What on Earth are you talking about? Those solo runs are solo because they are so exceptional.
