2) In 1976 world championship final, Higgins not conceed early before Reardon had "reached the winning post". Reardon won the frame he needed to win the match 27-16. However, Higgins did conceed several frames early when he could still have techniclaly won them.
3)While it is correct that Higgins was ranked number 2 on two occassions (since the ranking list was created in 1976) it is worth noting that for the 1982 / 1983 list, Higgins had two ranking points deducted for misconduct. Otherwise he would have been ranked number one, based on tournament performance.

The article does not list many of Higgins' tournament victories. I would suggest adding:
