How much insulation did you use under the slab and footings?

Curious about slab insulation and if you used a "Frost-Protected Shallow Footing" system.

    Frost Level is 18" where we are.
    The bottom of the insulation for the footing is 20" from grade.
    R32 around footings and R40 under slab.
