In 2010 it was found that the University of Wyoming's Balloon Trajectory Forecasts were very accurate. For the May 16, 2011 launch our ascent rate was much slower than the default, and unchangeable, ascent rate used by the University of Wyoming and thus our balloon went much further than predicted.
For 2012 Launch, Predictions were made using the University of Cambridge's balloon tool. This change was made for the following reasons.
- wind predictions found to very closed to the University of Wyomin's tool
- University of Cambridge's tool Allows for two addtional inputs of ascent rate and decent rate
- University of Cambridge's interface allows for point and click setting of launch location using google maps
