I agree with your grade, with the caveat that apparently clearing the pad was the requirement for success.
I think you may have missed the joke, though. Oh well ...
No i didn’t miss it. I knew some one was going to bring that up.
Clearing the pad was not the mark - it was not exploding at altitude as that would have killed many like N-1 did, destroyed the town of Boca Chica and the entire site.
