Mapping between instance_id of questions and their difficulty level?

[summerhare12]

Hi, in your paper, you have stated that

Difficulty level. We tokenize the gold SQL queries based on whitespace and classify their difficulty
according to the number of tokens: < 80 tokens as Easy, 80−159 as Medium, and ≥ 160 as Hard.

But I wonder if there is a clear map between the questions and their difficulty level, which you have already summarized?
It would be very kind of you if you could offer this, which will offer much convenience for us when sorting out our experiment results.
