But if the same energy is going in the room, won't it have the same
effect, Door open/shut? The furnace may still run it's normal cycle,
but should run for less? My gut says opening the door is better, but
I'm trying to think through the Math, and it's saying no.

your net energy consumption will be lessened by opening the door. with
it closed it wont change the ambient temperature enough to affect the
thermostat thresholds. With it open, it may raise them enough to delay
or skip a heating cycle.

Probably same net effect as you say.

We're in the single digits in chicagoland today, and I just made
my self lunch in my oven.
The oven is electric, so there is no outside vent. After I'm
done, should I open the oven door, to let the heat into the room
quickly, or keep it closed so that it radiates heat for longer?
I think that the math says that the same energy will be put into
the environment regardless, since there is nowhere else for it to
go. So will the room be warmed by the same amount if i keep the
door closed vs open?
The things I think about when I'm hungry....
