That's not particularly surprising. But you may be asking the wrong question.

If you want to know whether the rules are clear then I think that the right question to ask is not "Are the answers crystal-clear to you?" but "Will different people produce the same answers?".

If we had a sharp drop in the graph at one point then it would suggest that most everyone has the same cutoff; instead we see a very smooth curve as if different people read this VERY SIMPLE AND CLEAR rule and still didn't agree on when it applied.
