• Ping: Round-trip latency (trimmed mean of 20 samples)
• Jitter: Latency variation (mean absolute deviation)
• Download: Multi-stream download throughput
• Upload: Multi-stream upload throughput
• Bufferbloat: Latency increase under load (graded A through F)
• Experience Scores: 4K Video, Video Call, Gaming, Web Browsing (0 to 100)
