How is that ambiguous, when they're stating something more clearly by saying that?

Whatever benchmark you use, you keep using the same benchmark, then it's as meaningful as it can be.
It is all an imprecise science, all they can do is state as many perceived facts as they can, in the clearest way.
If there's any obfuscation they get questioned on it, and this has been the case with whether they acted fast enough etc.
But that's all water under the bridge and will be the subject of endless post-mortems when the time comes.
In the meantime, all they can do is number crunch the daily stats and base future actions on them.
