I also agree that you should keep it simple. Also, remember that the importance level determines just what it says and the velocity goal should be set according the type of work running in the SC. Don't set the goal based on the importance of the work. Assuming all 6 service classes run similar batch work I would set them somewhat as follows. Remember that this all depends on your shop and what is important to you. However, normally CICS, DB2, MQ, and other subsystems like that are the most important work in any shop; so I wouldn't give any batch work an importance level of 1. You might set up a HOTBATCH at importance level of 1 to more very, very, very special batch work into (like the CEO's special job :-)).
BATHI and BATWLMHI - IMP 2, Velocity 30 BATMD and BATWLMMD - IMP 3, Velocity 30 BATLO and BATWLMLO - IMP 4, Velocity 30 And, once again, everything is dependent on how your shop wants to run.
