Bags are rated at survival temp not comfort rating..a zero bag will be good for low 30s Mid 20s for comfort level depending on the person.....if u want to be warm in the cold you need a negative bag..If u want to warm up a little throw a hot hands in the bag it will increase your comfort level a few degrees...
I usually run a gas powered sack heater.
Kick start due to high compression.
A handwarmer or two in the bag (one by the feet, one by the chest, never on bare skin though) was a pretty good trick in the military that let me use a 30 degree bag in the field if it was colder than expected. Hot water bottle also works well, if time consuming to boil.

Foam is the answer.Foam pads don't slip, don't hold air, and flat out insulate.Sleep on a foam pad=Sleep warm.R value is R value. It's not relative to material when comparing equal values.I agree that Foam is more comfortable, and doesn't slip like air pads. Pad slipping is one of my main sleep issues when in the backcountry, but certainly not worth packing in a bulky foam pad. I'd add that a few minutes of site prep alleviates a lot of pad slip. Start with a flat spot and you don't slide around near as much. Some simple strips of leuko tape also nukes the issueSome stripes of seam sealer works wonders as well 😉
