The saved baseball model first converts exit speed from miles per hour to feet per second using one point four six six six seven. One hundred miles per hour becomes one hundred forty-six point six six seven feet per second. It splits that speed into horizontal cosine and vertical sine components and begins three feet above ground. These are inputs to a toy numerical model, not a measured hitter forecast. A second illustrative fifty-mile-per-hour input converts to seventy-three point three three three five feet per second. Both bars use four pixels per foot per second, so their widths have the same units and the expected two-to-one ratio. Wind changes the relative horizontal air speed before drag is computed. A horizontal speed one hundred feet per second with ten-mile-per-hour outward wind gives eighty-five point three three three relative feet per second. Drag magnitude is proportional to relative speed squared. Holding all other factors fixed this is about point seven two eight of the no-wind drag. The model also includes vertical air speed, so this illustration isolates the horizontal case. The bars show relative drag, not relative speed: the no-wind case is one hundred percent and the isolated horizontal wind case is about seventy-two point eight two percent. Both use six pixels per percentage point. The source advances velocity and then position every point zero two seconds. With an illustrative constant acceleration negative ten feet per second squared and initial horizontal speed one hundred, the next speed is ninety-nine point eight and the step distance is one point nine nine six feet. Real source forces change each step. The normal wall-crossing branch records the first sampled crossing height. If the final distance passes the wall while the stored height is exactly zero, a separate fallback interpolates between saved points. Output precision therefore does not establish physical accuracy.
