Your right, I did assume the rate would be constant going forward. However, I assumed that the rate of change (RoC) would be the highest now than later. This is the data from the largest kickstarter "Pebble: E-Paper Watch for iPhone and Android": http://www.kicktraq.com/projects/597507018/pebble-e-paper-watch-for-iphone-and-android/#chart-exp-projection http://www.kicktraq.com/projects/597507018/pebble-e-paper-wa... If you notice, the earliest part of the campaign has nearly the highest RoC. Towards the middle, it kind of flattens out. And, as you mentioned, towards the end (the uptick) the RoC resembles that of the beginning of the campaign. If everything remained constant for the next 27 days, that "uptick" would have to be >$10 million dollars on that last 3 days. Still, they will beat the largest kickstarter campaign ($10 million).
