Here's a quick summary about priorities -

It may be possible to cons up a config that would approximate your 
rules, but it will be prone to errors and may violate some other 
unstated rules.

If you really want to try, you should start by submitting all jobs with 
the same +AccountingGroup attribute. FYI, this means no accounting is 
reported between users. You might extend it by adding AccountingGroup to 
your SUBMIT_EXPRS.

FYI, the <30s SLA is only achievable when you have excess capacity.

Best,
