4.4 Defining Categories—Initial Definition
When initially defining the categories for inventory analysis, first
estimate the average value and range of each measured property for
the bales in inventory.
• Use the values below to initiate histograms for each fiber property
according to the procedures outlined in this section. Most actual
inventories cover a much smaller range.
Note: When beginning, all categories should be set to “20”.

Note: These are NOT the recommended category definition values.
Use these values only in the very beginning in order to study the
distributions of each measured fiber property.
