Note that Lie's personal records on the 1,000 m, the 3,000 m, and the 5,000 m were not world records because in all three cases Laila Schou Nilsen skated faster at the same tournament. Nilsen's respective times were 1:38.8, 5:29.6, and 9:28.3. Also note that the Old combination was not an official world record event, as governed by the International Skating Union, until 1949.
