to me as if it is a large drop.  Unfortunately, no one knows the
significance of any counted drop.

Response:
True, not the exact significance. But to me there are three
conditions: 1. No mites (you don't need to treat). 2. Some mites
(better treat). 3. A lot of mites (completely out of hand, maybe too
late).
