Dead zone between -1 and +1 in rating graph

[dfannius]

The region between -1 and +1 does not exist in AGA ratings, but it exists on the rating graph, making it look like someone who goes from -1.05 to +1.05 has gained 2.1 stones in strength rather than 0.1. http://agagd.usgo.org/player/20880/ is a good example. The y axis of the rating graph should not contain the region between -1 and +1.
