This is because, when notation is a mixture of literal chars, and char
ranges, that the raw totals don't always reflect what you would
intuitively think. If a pattern with CID match adds up to around 20
chars, to make the NZX notation stick out, use numbers near 100. That
way, their contribution to the count is hard to lose in the totals. I
will probably also make the [0-9] type range notation have a similar
weight near 100 before I'm finished.
