@gnunes: can you run your trajectory program with the following parameters, and post height vs distance data (say, every foot) and a PNG of a plot of height (above the launch point, in feet) vs distance (horizontal distance from the launch point) with the following parameters: Vo=23 feet/sec, theta=45 degrees, g=-32 ft/sec², drag = -0.03*V² ft/sec², and no spin?
