Too hard for CCLP1?

[AdrenalinDragon]

Ok, there has to be a way of judging which levels fit CCLP4 better than CCLP1. Something like Skydiver's Maze and Fireball Maze for example, I see as too hard for CCLP1 and would vote against it for that reason, but everyone seems ok with it. How are people going to work out what fits CCLP1 criteria without being a borderline CCLP1/CCLP4 level?

EDIT - I hope I'm not offending the designers, because I like these levels. It's just I feel they're more CCLP3/CCLP4 than CCLP1 difficulty, if you catch my drift.
