If timing is advanced and temperature high you will get better FC.

Your right, driver can affect the MPGs achieved hugely. I'm not talking about that though. I'm talking about how the vehicle control system adds more fuel during cold starts to ease startability, and avoid rough idle. Like you mention this is mainly due to a cold combustion chamber. What is FC?
