Reply to comment by Mystic_L in NASA Moon mission 'exceeding' expectations by modrosso

"Exceeding expectations" in this case means things like "We expected this part to have maybe 5% variance from nominal, and designed to cover worst-case scenarios within that range, but it was more like 2% from nominal because a bunch of stuff worked extremely well." Not "it went way faster than we expected and we don't know why, might overshoot moon idk."

In this case, (with the recent info from the press conference), SLS performed within 0.3% of projections, and neither it or Orion have had any major issues (fingers crossed!). For the first launch of a fully-integrated launch vehicle and payload, that's super impressive!
