我正在尝试查找每一位玩家每天得分的平均值。一个例子如下：
Date Player RPE Score Post Score
--- ------- --------- ----------
8/26 Player 1 3 5
8/26 Player 2 4 6
8/26 Player 3 7 6
8/26 Player 4 2 9
8/27 Player 1 4 5
8/27 Player 2 - -
8/27 Player 3 8 3
8/27 Player 4 1 2
8/28 Player 1 5 1
8/28 Player 2 4 9
8/28 Player 3 - -
8/28 Player 4 0 4
我想使用Excel，这样我就可以轻松计算每个球员的平均RPE和发布得分（每4行），因此看起来像这样：
Player RPE Score Post Score
------- --------- ----------
Player 1 4 3.67 (11/3)
Player 2 4 7.5 (15/2)
Player 3 7.5 4.5 (9/2)
Player 4 1 5
任何帮助将不胜感激。谢谢！
