Alta's graph on that page is scaled inappropriately for its current
performance level.  Follow the link at the top of the page to the
Alternative Presentation and you'll find a graph of alta with a more
useful scale (albeit also a different style with the absolute value of
the offset as the Y scale and a different color to indicate
negatives).
