Wusage 7.1 Manual
If you prefer to manually edit your configuration files, use the following syntax for this option:
trailwithminimumsteps 3 (whole number, 1 or more)Description
The Top Trails-With-Certain-Documents Report: Minimum Steps (trailwithminimumsteps) option indicates how many steps must be followed in a user's visit for that "trail" to be included in the Top Trails-With-Certain-Documents Report: Patterns (trailswith) top-trails-with-certain-documents report. By default, wusage sets this option to 3, because shorter trails are usually not of interest. However, you may wish to set this option to 1 or 2, or to a higher value. You may specify any whole number of steps. See also the Max. Minutes Between Accesses (trailtimeout) option.
