We have following jobs in queue:

-- job 2 for project 1
-- job 3 for project 1
-- job 4 for project 2

-- job 6 for project 3
+- Job 1 for Project 1
+- Job 2 for Project 1
+- Job 3 for Project 1
+- Job 4 for Project 2
+- Job 5 for Project 2
+- Job 6 for Project 3
With the fair usage algorithm jobs are assigned in following order:
-1. We choose job 1, because project 1 doesn't run currently any jobs and has the lowest job number from projects that doesn't run jobs
-1. We choose job 4, because project 2 doesn't run currently any jobs and has the lowest job number from projects that doesn't run jobs
-1. We choose job 6, because project 3 doesn't run currently any jobs and has the lowest job number from projects that doesn't run jobs
-1. We choose job 2, because project 1 as other it runs 1 job
-1. We choose job 5, because project 2 runs 1 job, where project 1 runs 2 jobs now
-1. We choose job 3, because project 1 and runs 2 jobs
+1. Job 1 is chosen first, because it has the lowest job number from projects with no running jobs (i.e. all projects)
+1. Job 4 is next, because 4 is now the lowest job number from projects with no running jobs (Project 1 has a job running)
+1. Job 6 is next, because 6 is now the lowest job number from projects with no running jobs (Projects 1 and 2 have jobs running)
+1. Job 2 is next, because, of projects with the lowest number of jobs running (each has 1), it is the lowest job number
+1. Job 5 is next, because Project 1 now has 2 jobs running, and between Projects 2 and 3, Job 5 is the lowest remaining job number
+1. Lastly we choose Job 3... because it's the only job left
