[Cake] Advantages to tightly tuning latency

[Justin Kilpatrick]

I have a frequently changing link I'm using automated tools to monitor and tune using Cake. Currently I'm only tuning bandwidth parameter using latency and packet loss data.

My reading of the codel RFC seems to say that trying to tune the 'interval' value using known path and link latency won't provide any advantages over just tuning the bandwidth parameter.

Obviously codel is just one part of the Cake setup and I'm wondering if there are any advantages I'm missing by not providing this extra input using data I already gather. 

Thanks!
