Says who?
You haven't yet used your PTM (Personal Time Machine) to jump a day to see results? Okay, you got us. Yes, you can see the results. But the problem is that somehow the Universe detects that we have tried to cheat for financial gain, and intervenes to make the game unpredictable again. We think this is currently caused by a combination of factors - the current polarization of Earth to the North, the flow of the Precession (galactic rotation), BSPN anti-Cowboys bias level, and the current percentage of Earth women with implants. However, we are working to resolve this interference with the LHC (Large Hadron Collider). That is the REAL reason for the LHC. Oops, I wasn't supposed to let that out. Don't tell anyone you heard it from me.
