Just after SRB separation on Discovery's launch, Capcom informed the
shuttle crew: "First stage - nominal."  Shortly thereafter, Capcom came
back with a revised evaluation that first stage performance was "low."
Interestingly, the CNN people didn't pick up on this and nothing else
was exchanged between the crew and ground (at least nothing that CNN
aired) on the subject.

What is considered in this evaluation?  Was the SSME and/or SRB thrust
too low?  For that matter, how much is "low?"
