I'm assuming nothing since all we have is your word for it.

You'll have to excuse me if I take that figure with a large packet of salt
unless the code does nothing particularly complicated.

Why not? Many large companies have automated build systems that could be 
building many projects many times during the day as people check in code 
updates. Not rebuilding code that doesn't need it saves CPU time and hence
power usage.
