Outside
T is probably 65 when I bring it in, and upper 70's, maybe 80 when I
bring it out. (All T's in Fahrenheit)


Unless I'm missing something, the answer is right there.  If you deflate it at 65F, the air will have expanded a bit when it is
warmed up to 75-80F.

I don't deflate it/reinflate it daily. Just fill and empty with water.
The water is tap-cold (not sure of the temp of that, but cold to touch) and gradually warms up during the day, but is consistently cooler than the air.
I think that's what I wasn't considering- the heat sink of the water. Maybe. I'll ponder that some more.
