I believe the purge should last for half of a week with only initiation rules and no sops and a half week with no rules, KOS, no sops, etc. However, I think there should be some breaks in the all out warfare and allow staff to hold events as a break to the madness. Possibly some car races, helicopter battles, majors, etc. The purge should last no longer than 1 week to avoid redundancy as some people can get tired of the all-out warfare pretty quickly.
