I’ve haven’t actually run the site but according to various wiki’s the Blood Port anomaly should escalate to DED 7/10 site, Blood Raider Coordination Center. As far as I know CCP hasn’t done any major changes to Exploration sites so I’d say the various wiki’s are still close to being accurate. However I believe CCP does regularly change the RNG tables for both loot drops and escalation chances.
Hopefully someone with experience in running Blood Port anomalies will post a reply and either confirm or deny if the site still escalates to a DED 7/10. If nobody does then you’ll just have to keep running Blood Port anomalies until you get an escalation, then you’ll know for sure.
