リファレンスの説明と例は英語です。見出しと目次は日本語です。

難しさ: how hard an example sentence is to read, so the easiest one can lead.

A character like 水 appears in thousands of example sentences, and showing whichever one a database returned first hands a first-grader a sentence built from rare name kanji. Score each sentence once (when it is added, say) and the query is a plain sort.

Two things make a sentence hard: how long it is, and the hardest character in it. Length is the honest baseline, since a short sentence is readable even when every word is new, and the hardest kanji dominates, because one unknown character stops a learner as surely as ten do.

What a kanji costs comes from the school grade or the frequency rank you hold for it (KANJIDIC2 has both). The package carries no table of its own.
