本研究之目的旨在探討常規統計與新統計方法之三段技術，以韓國桌球運動原李廷佑在2005年中華台北桌球公開賽四場比賽得分率與使用率平均值的表現分析探討，其研究結果如下：
(一)李廷佑是以發球搶攻段及接發球搶攻段為主要的得分技術手段，無論常規統計或新統計方法，他在前兩段的得分表現皆具相當高的程度及穩定性，但在三、五板及四、六板的進攻銜接尚未成熟：相持段依然是他最弱的階段，技術表現都屬不及格指標值，為此以提供我國運動員日後對陣時參考。
(二)新統計方法能夠有效的觀察桌球技戰術中的第三、五板及第四、六板技術的質量和銜接質量，有助於對運動員進行技戰術的診斷與分析，並為桌球三段技戰術評估體系，提供參考依據。 The purpose of this study intends to explore the three – staged techniques employed in regular statistics vs. those of new statistics formula. And the average scoring rate and usage rate performance analysis in four matches for Korean athlete Lee Jung – woo who attended the 2005 Chinese Taipei Table Tennis Tournament were explored and the findings are as follow：
(1)Lee Jung – woo primarily employed the scoring techniques like the stage in serving the ball to attack in addition to stage in receiving the serve to attack. It does not matter whether it employs regular or the new statistics method, his scoring drives in the two previous stages exhibited considerably high level and stability wise. Nevertheless, in the combinations of third, fifth and fourth, sixth strikes, his techniques were found as rather immature. And during the stalemate stage, it is generally treated as his weakest with technique performance rated less than qualified at best. And these observations were expected to be used as references for our athletes in the future.
(2)The new statistics method can allow effective observation for technique and bridging qualities for the third, fifth strikes and the fourth, sixth strikes during table tennis match tactics deployment, and it is definitely facilitating the techniques tactics diagnosis and analysis for athletes in proceeding to technique tactics training. In addition, this research is expected be used as references for deploying the table tennis three – staged tactics assessment system in the end .
