Okay, so:
- The proportion of requests that succeed, local or not. Higher is
  better.
- The maximum number of requests started. Infinity is too high, however
  if this is high, pSuccess will be low.

If a simulation shows high requests started only because of an artefact
(lots are being started, none are finishing), then that's an artefact
and it needs to be dealt with e.g. by allowing all requests to finish
before computing the total psuccess.
