Comment (by asn):

 Hmm I can see how that makes sense. However, if we are trying to provide
 security for such tiny networks (30 nodes) we would probably have to
 change the rest of our guard picking strategy quite a bit as well.

 Anyhow, no strong opinions here and the code seems reasonable.

Comment (by nickm):

 Maybe.  I'm thinking that there are network sizes where the fractional
 restriction matters more -- like on a 30-node network, for instance.  At
 least, that's what I had in mind.

Comment (by asn):

 I wonder if the fractional restriction is any useful now that we have the
 absolute restriction. In most cases the absolute restriction will take
 priority over fractional restriction (20% of total guards is like 110
 guards right now).

 I feel like the absolute restriction is more accurate and powerful. Maybe
 we can kill the fractional one to reduce code?

 Perhaps it would make sense to introduce the fractional restriction if it
 was based on guard bandwidth and not just number of guards.

 the current value of 0.3.0 in my prop271_030_v1 branch is ridiculously
 large.
