In a computer system, methods and computer-readable medium are disclosed for tracking motion of a subject in an activity captured by camera. The camera supplies pluralities of discrete images of the subject to a computing system environment. An event window has at least two cells for receiving a user input pertaining to an action of the subject in the activity. In a first cell, the user indicates a specific image number corresponding to one of the plurality of discrete images and an estimate of a fractional percent thereof. In the second cell, the user indicates another specific image number and estimate of a fractional percentage thereof. Software calculates deltas between the cells. Pushbuttons are provided to aid users in navigating between pluralities of the discrete images. Example subjects include horses in horse race activities while actions include horse stride length.
