You are right of course, Sandman. This is where the analogy comes to its limits.
On a second thought, if a woman gives birth to quituplets, it will take nine months (probably even less), but the babies will have to be under certain medical treatment in a clinical fab – something that could not be done with the equipment in the lab at home. (Okay, okay, I admit I am really pushing the analogy's limits hard here. ;-))
