Not sure how new this is but there's an interactive news release/price chart up on SGR's website. Judging by the news flow, when they want to run the price, they release lots of news. When they want to slow things down, they trickle it out. Rocket science.

ALso interesting that every news release has a subject line except the Hinge Bulk Sample. Instead it is listed only as July 14, 2009
