How well do accumulated GDDs relate to approximated and actual growth and development of the 2015 corn crop?

Most corn producers are aware of growing degree days as a way to both monitor the accumulation of heat units favorable to growth and estimate when a crop may reach important developmental milestones. Briefly, to calculate the GDD value for a particular day, the daily high and low temperatures (between and including a low of 50 and a high of 86 degrees) are added together, divided by 2, with 50...
