Judging the difficulties by success rate:

Very easy: At least 95%, should only take 1 attempt (2 if unlucky, rarely 3)

Easy: 75~95%, 1 or 2 attempts (up to 5 if unlucky)

Considerably easy: 55~75%, 1~5 attempts (up to 10 if unlucky)

Medium: 35~55%, 2~7 attempts, can also include unclear difficulty levels.

Consideraby hard: 15~35%, unlikely to pass on 1st try, probably 3~15 attempts.

Hard: 5~15%, usually takes 5 lives or above, probably 5~25 attempts.

Very hard: 2~5%, passing on first try is considered lucky, mostly 10~50 attempts.

Insanely hard: Less than 2%, extremely frustrating, 20~100~+ attempts.

For me I do have some overlapping areas, because there are some that took me less tries but can actually feel the difficulty of a certain level, and some that took me more tries but just don't understand why I can't pass the easier levels easily.
