How do I count fruits for Gregg's mistflower, Conoclinium greggii?

Ok I just read the fruits definition and it says - 

One or more fruits are visible on the plant. For Conoclinium coelestinum, the fruit is very tiny and seed-like and is crowded into a spent flower head. The seed-like fruit has a tuft of white hairs and changes to grayish-brown, and drops or is blown from the plant. Do not include empty flower heads that have already dropped all of their fruits.

So I think I would count the things circled in white in the attached photo as one fruit.

I'm going to estimate how many fruits are in a couple of the spent flower heads and then multiply by the number of flower clusters in the patch I'm tracking.

Most plants in the Asteraceae will have involucres with many individual flowers that mature into individual achenes with some kind of pappus. Dandelions and sunflowers are well-known examples. In our observations, Ericameria has this type of fruit.
On the other hand, our showy milkweed (Asclepias speciosa) has heads with many flowers that usually only have one or two fruit pods. When those open, hundreds of tufted seeds are dispersed. That leads to observations of perhaps 6 ripe fruits, but then 11-100 recent fruit or seed drop.
