- Permissions: The job_sort_formula must be set by the admin (e.g., root)
- Summary: Number that allows two entities to be directly compared
- Details:
- A number between 0 and 1. Lower numbers are less deserving

- Low usage entities from high usage groups are negatively affected by their siblings.
- If any job's entity has 0 shares, this keyword will resolve to 0.

There is extra quoting which is required to use formula math. Here is how it is done: qmgr -c 'set server job_sort_formula="pow(2, -(fairshare_tree_usage/fairshare_perc))"'

Example:
Share numbers do not need to add up to 100, it just makes the example easier to understand. Entities don't need to all be at the same level of the tree. For example, root could own an entity.
