You can make sure that all the points will be visible (without changing the window values manually) by pressing "ZOOM" then choosing "ZoomStat" or 9.

The revenue will reach 500 billion at exactly 2006.15 years. Which would be the year 2006 NOT 2007

I've just reset my calculator and when it got to the Vars segment, absolutely nothing happened the way it was described in this video. Nothing saved in Y1 and I tried it, key for key 5 times.
