Using Flent 1.3.0 on macOS 10.12.6:

I notice that the "TCP upload sum" value shown in the upload portion of tests (tcp_nup, rrul, rrul_be) doesn't match the sum of the individual flows. In the first example below, the displayed sum (0.28 Mbps) is considerably lower than the sum of the individual flows (0.77 Mbps - which matches the expected speed of my 7Mbps/768kbps DSL link).

I attach the flent.gz and the log files from the first run shown below. (Earlier rrul and rrul_be test runs follow.) What other information could I gather? Thanks.
