You can change that '20%' threshold by editing this:
UWCS_PREEMPTION_REQUIREMENTS = ( $(StateTimer) > (1 * $(HOUR)) &&
RemoteUserPrio > TARGET.SubmitterUserPrio * 1.2 ) || (MY.NiceUser ==
True)

So, you could increase '1.2' to something like 1.5, or 2.0, etc.

Also, you can make use of:
# allow up to 24 hours for a job to complete after initial preemption:
MAXJOBRETIREMENTTIME = 3600 * 24
