For TX, each latency measures the time from command submission to completion event -- when multiple packets are in-flight simultaneously these overlap, making the sum much larger than wall-clock time and deflating the reported speed. For RX the inter-arrival sum roughly equals wall-clock time. This asymmetry caused the same data stream to report vastly different speeds depending on direction. Fix by computing speed from wall-clock duration (last packet timestamp minus first packet timestamp), which gives consistent results regardless of direction. Also add 1-second windowed throughput tracking to report min and max speed alongside the average.
