Description

Something is rotten with the bwauth feedback experiment. My current best guess is that we can't properly measure the occasions where fast nodes *do* get overloaded, because we don't measure often enough.

One way around this would be to only perform positive feedback for nodes using a filtered measurement set containing only the *slow* measurements (below mean) for each node.

This is a relatively simply change. We can just duplicate filt_bw in the bwauth children as slow_bw, and change the filtering step to be < avg rather than > avg.
