When a project is created, its tasks are assigned a priority by default. If you have permission to do so, you can change the priority of all the tasks within a project from the Projects List, or of individual tasks from the Tasks List. Changing the priority of all the tasks contained by a project will also change the project priority and viceversa.
Different bands are created and written to the configuration file. The lower and upper limits of bands specify the number of tasks that a project must have that so that the project tasks are assigned a particular priority. For example, the following information exists by default in the configuration file regarding task bands: 10, 20, 50, 100. This means that the existing bands are 0-9, 10-19, 20-49, 50-99, 100 - no upper limit. There are as many priorities as there are bands, and these are by default 1, 2, 3, 4, and 5. Priority 1 corresponds to the band 0-9, priority 2 to the band 10-19, so on. Higher priorities have lower absolute numbers. For example, tasks with priority 1 are the highest priority and will be processed first. Therefore, if a project has eight tasks, all of its tasks will have priority 1. If a project has 21 tasks, all of its tasks will have priority 3.
