 Isn't this the documented behavior of -n in renice(8):
 
      -n      Instead of changing the specified processes to the given prior-
              ity, interpret the following argument as an increment to be
              applied to the current priority of each process.
 
 Does renice work as desired if you omit the "-n" from the command line?
