Why such disparity? Because each model works a bit differently and depending on the model used and assumptions added in, the results will change, sometimes dramatically. 

Now 31 leaders in computer modeling science are calling for an open exchange of the computer models and code that are devoted to assessing and predicting the path of COVID-19. A letter to Science magazine, written by C. Michael Barton, director of the Center for Social Dynamics and Complexity and a professor in Arizona State University’s School of Human Evolution and Social Change, and other leaders in computer modeling, states that given the gravity of the situation, the traditions of science necessitate a free exchange of computer modeling information.
