"I would think that time to show a slightly changed page after a "refresh" or "reload" would be appropriate. What are the other choices?"
Well, what we really want to measure is the overall effect so that we can see how Railgun improves things in general. The 'refresh' time is interesting, but we're also interested in the network scale (how does user X downloading Y improve the speed for user Z downloading the same (but slightly different) page Y).
"but in the base case there is only a single proxy and hence no extra connection time to consider"
That isn't really the base case. The base case is that we need to go get the resource with a normal HTTP connection direct to the server.
