Using Flent 1.9.9-git-2a08dd9:
I have been looking hard at Flent results for Dave's tests for coffee shops
[(my latest script.)](https://github.com/richb-hanover/coffee-shop-bloat-test)
I have a few fussy observations about the Flent output for the tests:
* I like how the rrul and rrul_be tests summarize average and sum as the last
items in their section. My eye is drawn to the discontinuity in the labels and
sees the sum (after all is - that's the only number people care about :-) at
the bottom. In the tcp_nup and tcp_ndown tests, it occurs to me to place the
average & sum at the bottom of those lists as well.
* I believe (but am guessing) that the rrul and rrul_be "TCP totals" row is the
sum of the TCP download sum and the TCP upload sum. It occurs to me that
statistic could be placed at the very bottom of the report instead of being "in
the middle".
* It would be helpful not to add a closing "." after the filename in the "Data
file written to..." line. That makes it easier to select the file name for
pasting into `flent --gui ...` command. Mistakenly copying the "." doesn't seem
to hurt, but I perseverate about having that "." in the file name.
As always, Flent is a great system for collecting and displaying reproducible
data. Thanks.
