Ashania,
Did you experience the actual ‘several thousand ms’ issue with either of these tests? Thus far everything seems reasonably within tolerance within your area. There’s still packet loss I’m slightly concerned about but nothing that jumps out and says “Yeah, that’s the problem.”
You also mentioned that you had some higher performance delay than your latency showed. Are you seeing that just in certain areas/fighting certain bosses, and is it consistently a problem when you do that content?
