Inception: nuts and bolts

I went to see Inception for the second time - just as enjoyable as the first time, and I absorbed a lot more of the universe rules this time around.

Unfortunately, *that* meant discovering that Inception Math timescale thing that has been linked in every pimp post and picspam I've seen so far, which I have been basing all of my mental math on?

It's wrong! At least, wrong during the Fischer job. And during any dream sharing that isn't Ariadne's training.
