[Codel] what RTT was fig 7 in the codel paper?

What RTT was fig 7 in the codel paper? (the one that showed codel's
reaction to bandwidth changes?)
http://queue.acm.org/detail.cfm?id=2209336

I am amusing myself by trying to create an automated string of flent
tests to duplicate those results, now that flent has gained tools that
can plot queue depth as well as ping, we have a testbed with fully
controllable RTT, etc.

"To roughly emulate a (nominal) 100-Mbps Wi-Fi link subject to
degradation, we used a load of four FTPs and five Web connections per
second and changed link rates at 50-second intervals (over the 300
simulated seconds), first dropping to 10 Mbps, then to 1 Mbps, then
jumping to 50 Mbps, dropping to 1 Mbps, and finally jumping back to
100 Mbps. Buffer capacity is a single BDP (830 packets) for the
nominal rate. This scenario was repeated for CoDel, Tail Drop, and
RED. "

Oh, that would have been 100 ms unloaded.
