If you want to set the multiplier for a user you can use the
Lets say I have a user who's a light user of the system (so their Real
User Priority is always high because they don't run many jobs) but I
don't want them to be able to take over the system when they do submit
jobs. I want the system to *think* they're a heavy user at all times.

Priority is always lousy (i.e. always high):
