Our algorithm has various levels of customization which can be visualized in the Drilldown under "Custom Categorization Status". This article outlines the four types of categorization statuses.
The default algorithm will account for most of your time. Default algorithm means there is no custom categorization in play and the time assigned to this category has been classified according to our algorithm.
If you have LBAM (Look Back Adjacency Matching) enabled you will see time in the category "Adjacency matched". This time was previously considered "Uncategorizable" by the algorithm, but through the LBAM has been assigned an activity.
If you have specific activities you would like to exclude within Clocktimizer, we can do that through activity exclusion. Activities can be excluded on multiple levels, more information on that in this guide. Time that has was previously assigned to an excluded activity will appear in the category "Custom rule".
Regardless of which custom categorization method you're making use of the original categorization by the default algorithm will always be available by selecting "Original categorization" in the Partition By... section of the Drilldown. You can review the original categorization of time that was altered due to a custom rule, LBAM, or manually recategorized by filtering on the custom categorization status, then partitioning on activity.
