Whats the quantum time? I'll assume its one. Try posting your answers here instead of attachments.

Your queuing is inconsistent.
cycle 0 : queue job 1, do work on job 1. Job 1 not finished so requeued.
cycle 1 : new job inserted in front of queue (job 2). Work job 2. Job 2 not finished requeue.
cycle 2 : no new job. Do work on Job 1. Job 1 not finished so requeue.
cycle 3 : new job inserted at end of queue. Work job 2, requeue job 2.

Why is job 2 inserted before job 1 at step 1, but job 3 is placed at the end in step 3?
