1. A method of evaluating a data capturing system of a forms processing system including at least one of an optical character recognition system engine and a Key From Image system where image snippets appear to Keyers on computer screens comprising steps of incorporating simulated forms data as images image snippets of predetermined contents into a workflow of the data capture system; the simulated forms data image snippets being computer generated from the predetermined contents, supplying truth data corresponding to the predetermined contents of the simulated forms data image snippets to an electronic scoring module in an electronic digital form, interpreting the simulated forms data image snippets within the workflow of the data capture system for inferring contents of the images simulated forms data image snippets through the at least one of the optical character recognition system engine and the Key From Image system where the image snippets appear to Keyers on the computer screens, sending the inferred contents of the forms data image snippets from the data capture system to the electronic scoring module in an electronic digital form, selecting benchmark comparison criteria through a graphical user interface in communication with the electronic scoring module, comparing the inferred contents of the simulated forms data image snippets to the truth data corresponding to their predetermined contents within the electronic scoring module, and scoring results of the comparison in accordance with the benchmark comparison criteria within the electronic scoring module for evaluating the data capture system, wherein the simulated forms data subject to interpreting provide statistically significant results.
