So ausführlich habe ich das mit Concord noch nie lesen können. Dank dieser Anleitung für das Ganken von Eisminern, lassen sich auch andere Aktionen besser planen.
Ganking relies on doing enough damage before CONCORD shows up and ends the party. That means if CONCORD is already in the belt, you can't gank: they will instantly jam you as soon as you fire. So if CONCORD ships are already in the belt, you need to move them out so you can get the full amount of ganking time.
In addition, the first spawn of the day will arrive 6 seconds early: it takes 6 seconds for CONCORD to warp once they are 'alerted' (alert time varies by sec status, anywhere from near immediate to 15+ seconds), but if they haven't been spawned they will merely spawn right on top of you. If you're the first person to gank in the system that day you need to "prep" the system: go get a newbie ship and shoot something in a non-ice belt or shoot a pos. Once you're destroyed, the system is ready.
