Previous projects had a peak at the start and the end - more like an inverted-U of activity. That all said, although the regression is probably not useful, the graph definitely helps indicate how much work is ahead of them. They've done a huge amount already (I believe they've broken some records already?) and to be so far off just indicates how crazy the target was. They're probably going to raise more than any other crowd-funded project, but it's a ways a way off.
