Are there stupid questions here? A staff answer, at length — that is the question, and I have not found it answered plainly anywhere I have looked.
Counting it rather than describing it, because the count is the part that can be argued with.
28 instances over 6 weeks, recorded the same way each time, 2 of them different enough from the rest that I have set them aside and said so.
That is the whole dataset. The question in the title is what it does and does not support.
