I just found out that my gunite was shot on 2 separate days with 3 days in between.
My pool builder told me that this is not uncommon for more complex projects.
I am just concerned about the structural integrity of the pool especially since it has an infinity edge on two sides, a wet edge on the remaining two sides, and is built into an elevated deck 12' above grade. The elevated patio area has had nearly 40 loads of dirt compacted, and there are still a few loads of dirt that will need to be added and compacted around the pool. I am a bit worried of a blowout when they compact this last bit of dirt.
Here is what the pool looked like after the first day of shooting:
