Hi Bob,

In Bounceback need per sample "To" and "from" latency. Currently BB reports To and from latency for complete time duration
0.00-30.04 sec OWD (ms) Cnt=300 TX=11.048/1.179/127.056/23.973 RX=3.910/1.095/19.869/3.098 Asymmetry=9.199/0.018/123.151/23.430

    Hi Bob,

    Can you please get "TX" and "RX" stats per sample ?
    Cnt=300 **TX=11.048/1.179/127.056/23.973 RX=3.910/1.095/19.869/3.098?

    Thanks,
