A method for determining a pump card for a well. The method comprising: obtaining a first set of data points, wherein the first set of data points comprise a first set of polished rod position data points of the well and a first set of polished rod load data points of the well; and calculating a first data point of a pump position and a pump load using the first set of data points. The calculating occurs before the well moves through a first complete stroke cycle.
