Coefficients and function fit for the asymptotic limit prediction.

Year calculated for achieving 99.95% of the asymptote with confidence interval (CI); b is the asymptotic limit; β is the progression range from the beginning of the event expressed as a percentage of the predicted asymptotic limit; β′ is the level of the actual BP expressed as a percentage of the asymptotic limit. Asymptotic limits b expressed in seconds for Oxford–Cambridge, Vasaloppet, Streif and speed ski record (for 100 meters); in minutes for the Hawaii Ironman and channel crossing; in hours for the Eastward, Westward transatlantic records and Elfstedentocht; in kilometres for the hour cycling records.

以置信区间（CI）计算得到的、达成渐近极限99.95%所需的年限；其中b为渐近极限；β为赛事起始阶段的进展幅度，以预测渐近极限的百分比形式表征；β′为实际血压（BP）水平，以渐近极限的百分比形式表征。各赛事的渐近极限b的计量单位如下：牛津-剑桥赛艇对抗赛、瓦萨洛佩特滑雪赛、施特莱夫滑雪道赛事及100米极速滑雪纪录以秒为单位；夏威夷铁人三项赛及横渡海峡赛事以分钟为单位；跨大西洋东行、西行纪录与埃尔夫斯塔德自行车赛（Elfstedentocht）以小时为单位；一小时自行车世界纪录以公里为单位。
