Oh no, I didn't. Should I draw a graph? Pop out some equations?
Let's say P is the nominal power. When I said "The other half" I meant when the solder iron is not plugged. So:
50% of the time at 4xP 50% of the time at 0...
Oh shizzzz, you're right!
I imagine this is more or less what it felt like to be in the room at the time. A whole group of people discussing electrical theory and optimal soldering techniques and meanwhile the one guy standing there holding the actual device notices the power cord is a little loose and pushed it in another 1/8" without mentioning it because everyone is so involved in their nerdy conversation.
Oh man I was going through it in my head too...
