You have fewer* misunderstandings ;)

In case your point is that using "less" instead of "fewer" for countable nouns is an example of unclear communication, let me disagree with the point.

Less so (more awkward) here than in other cases, but it's as if the misunderstandings were smaller in magnitude rather than quantity or frequency.
