I am pretty sure you need something like the following (courtesy of Reuti):

weight_tickets_share              10000000

weight_user                       0.900000
weight_project                    0.000000
weight_department                 0.000000
weight_job                        0.100000
weight_tickets_functional         100000
weight_tickets_share              0

policy_hierarchy                  F
