This morning I redid the challenge. Caityln made it out at 2310. I am so proud of my less sleepy, more practiced number.
Just for lurker entertainment, I did run an illegal sim through the challenge too. Sleep and practice overcame the advantages of the story mode sim in my case, but I did mess up that run badly. Having run both kinds of sims, I think the team made a good decision. Story CAS Kellie was able to overcome a major error compared to my sim running as smoothly as I could imagine.
It was a fun event.
