Comment (by nickm):

 Just skimmed the simulation code -- this looks like a plausible place to
 begin with the measurements. Do we have a plan to do these measurements,
 or should we make one?

 Also, I'm assuming that this simulation isn't trying to simulate the exact
 way in which guard sets change over time. If it is, we need to bring it
 into conformance with prop271.
