STAT The  state  of  the  task is shown here. The state is
            either S for sleeping, D for uninterruptible sleep, R
            for  running,  Z  for  zombies,  or  T for stopped or
            traced. These states are modified by trailing < for a
            process  with  negative  nice  value, N for a process
            with positive nice value, W for a swapped out process
            (this  does not work correctly for kernel processes).

The fluctuation of a process' dynamic priority is regulated by another value: The "nice" value. The nice value is an integer, usually in the range -20 to 20, and represents an upper limit on a process' dynamic priority. The higher the nice number, the lower that limit.
