Look, the figures don't match the amount in words.

看，这些数字和文字上的数字不符。

A phrase length is refers to these things that we call chunks, which is the amount of words in between two significant pauses.

短语长度是指这些我们称之为“块”的东西，即两个重要停顿之间的单词数量。

And so I added these pauses into my answer, and so the amount of words in between pauses therefore become smaller, so it nudges it down a little bit.

而我的答案中加入了这些停顿，所以停顿之间的单词数量因此变得更少，这就导致分数变低了一点。
