Using Flent 1.3.0 with fping 4.2 on macOS 10.2.6:

I see high ping times (>100 msec in the following report) despite the fact that actual ping times (measured by fping during the flent test) are 20-30 msec, and none higher that 47 msec. (I am on 7mbps/768kbps DSL, so the 6.95mbps seems accurate.)

Here is the data file. [tcp_ndown-2019-09-06T074544.888052.Rich_Test.flent.gz](https://github.com/tohojo/flent/files/3583797/tcp_ndown-2019-09-06T074544.888052.Rich_Test.flent.gz)

What other information could I provide? Thanks.

```
bash-3.2$ flent -x -H flent-fremont.bufferbloat.net -t "Rich_Test" --te=download_streams=4 tcp_ndown
