[gridengine users] Formula to calculate job's priority

The cluster is configured with share based policy (user based) with equal shares (100 shares) for all.
As per the below link:
The job's priority is calculated as follows:
prio = weight_priority * npprio +
weight_urgency * nurg +
weight_ticket * ntckts
Let's take an example, a parallel job of 20 cores to analyze this. There are no other requests like #$ -l in the script..
The value of npprio would be zero. Because there is no #$ -p <posix priority value> mentioned in job script & admin also does not set priority for a job manually.
nurg = normalized urgency
urg = rrcontr + wtcontr + dlcontr
There is no user configured under deadline users group. So dlcontr should be zero. ??
rrcontr = sum of all (hrr)
hrr = rurg * assumed_slot_allocation * request
rurg -> taken from qconf -sc | grep slots. 1000 is the value under urgency column.
assumed_slot_allocation = 20 (taken from #$ -pe orte 20)
request = NONE, hence it is 0 (There is no other resource request #$ -l )
Next is "wtcontr". How to get the value for waiting_time contribution? Is it calculated on this job only or is it a sum of waiting_time of all previous jobs by the same user?
I'm stuck here. Please guide me to do further calculation.
Thanks in advance
