I asume yes, but unfortunately hydra is not our most reliable 
infrastructure and we are in a process to replace it with berlin.

After authorizing both: run init with 
--substitute-urls="http://berlin.guixsd.org http://mirror.hydra.gnu.org";

Then your should see that guix looks for substitutes from both.

I usually pick a commit a week from master or so. The ability to say how 
many substitutes are available for a given commit has not been 
implemented yet.

In the best of worlds perhaps cuirass could compute this and show it in 
a new column here: http://berlin.guixsd.org/jobset/guix-master

Correct. Usually substitutes are build within a day or so of master if 
the infrastructure is working.

Check here e.g. http://berlin.guixsd.org/jobset/guix-master

Berlin is the fastest and is quite reliable. Hydra is a backup in my 
configuration but not needed if berlin is online.

This was not correct.
