I don't wish to name the system in case this is by design, but is it supposed to be possible to absolutely tank a system's primary faction influence from the upper 80s% to literally zero in one or two days? Pending states come and go almost randomly, and you literally cannot predict what the influence will be from day to day. It's a high-tech, high security system with 55 million people.
The issue is, the solo or private group players acting there as well.
Maybe people should only have an altering impact in those systems when playing in open mode. Otherwise one would never have a chance to know which group and how many currently do stuff at those systems as well.
