為何萌生出發明新的係數的想法，IPF官方給出了以下九點：

1.The current formula has been developed more than 25 years ago with data gathered between 1988 and 1994. The available dataset was not as extensive as it is today.

譯：當前的係數公式（指的是Wilks係數）是25年前利用1988至1994年間的採集的運動員數據為基礎設計的，這些數據放在今日並不具備廣泛性。

2.At that time, there were not that many women taking part in competitions; therefore only a small dataset could be used for the analysis, especially for women.

譯：當時（1988至1994年間）參加比賽的女選手比較少，所以僅有小部分數據可被用於分析利用。

3.The supportive equipment has made huge progress over the last few years.

譯：現如今支撐性裝備（用於裝備比賽）的材質技術突飛猛進。

4.Training methods have been improved and powerlifting became more and more professional.

譯：這些年來訓練方法得到了提升，力量舉運動的專業化程度越來越高。

5.Single championships in bench press take place on an international level. There has been no analysis how the used coefficient fits for single lifts.

譯：卧推單項現如今已經有了國際級別的錦標賽，之前並沒有分析過Wilks係數是否適合單項成績計算。

6.The first World-Cup Classic Powerlifting Championships took place in 2012 followed by the first World Classic Powerlifting Championships in 2013.

譯：第一屆無裝備力量舉世界盃在2012年舉辦，而接下來的2013年舉辦了第一屆無裝備力量舉世錦賽（說明：無裝備的世界級比賽是在2012年才開始的，之前的IPF比賽為有裝備比賽）。

7.Since 2016, the IPF competition calendar boasts World Classic Bench Press Championships for both men and women in all age categories.

譯：從2016年開始，IPF的賽程安排中出現了無裝備卧推世錦賽，且面向全年齡段的男女運動員。

8.The weight classes have been changed in 2011.

譯：重量級在2011年重新進行了劃分。

9.Humans have changed over the last 30 years: athletes have become heavier on average.

譯：在過去的三十年間，人類自身也有了變化，運動員的平均體重在上漲。

IPF係數的優勢在哪，官方給出以下五點：

1.Fair system for all lifters at all performance levels and for all sub-disciplines, not only the top lifters

譯：該係數對所有訓練水平的力量舉選手都適用，並非只適用於頂尖選手。

2.The new IPF Formula differentiates between men and women, classic and equipped powerlifting, classic and equipped bench press.

譯：該係數將男女，有無裝備，三項單項區分開來

（說明：這樣一來一共有八套係數：男子無裝備三項、男子無裝備單項、男子有裝備三項、男子有裝備單項、女子無裝備三項、女子無裝備單項、女子有裝備三項、女子有裝備單項；）。

3.Based on a data set of 20.000 individual best performances across several years

譯：公式的設計基於幾年來包含20000例比賽成績的數據集合。

4.Can be updated by simply changing the co-efficient on a regular basis

譯：更新公式只需簡單地修改一下參數。

5.Analysed and evaluated by independent scientists

譯：該公式由獨立的科學家們分析評估。
