1- when you shut down at night to 57, it takes 3 hours or more before the
temp hits 57 but in the morning when you bring it up, it rewarms pretty
much
in 15 mins or less.

I'm not getting this, can you explain further?

It takes a certain amount of time to reheat back to your 65 in the morning.
It takes a certain time to drop back to 57 when you cut the heat back.

Unless we know how long those 2 are, no one can answer your question as it
depends on the insulation and heating efficiency of your home.

The best any can do with what was posted is ask how long it takes to drop to
57, and how long it takes to heat back to 65.
