In a fibers-per-field calculation, how is the value of fibers per field determined?

Explanation:
The idea is to find the average number of fibers seen in each field of view. To do this, you tally all fibers observed and count how many fields you examined, then divide the total fibers by the number of fields. This gives fibers per field as a measure of how many fibers, on average, appear in one field. For example, 200 fibers across 25 fields equals 200 ÷ 25 = 8 fibers per field. Dividing fields by fibers would yield fields per fiber, not fibers per field, and multiplying or summing the counts doesn’t produce the per-field average.
