During presentation of an electronic form on a user interface device of a computer, a most likely input value for a first form field is estimated as the most often historically input value the in the first field, and the user's attention is re-directed to fill the fields in an order different from a natural reading order, according to the best available historical input patterns. This proposed auto-fill value is indicated on the electronic form associated with the first form field. If the user accepts, modifies or replaces the proposed auto-fill value, a most likely value for a second (next) field is estimated. The process is repeated for additional form fields until the form is submitted, saved, or otherwise completed, thereby using strong relationships between two or more input values for different fields as statistically determined from historical completions of the electronic form to predict and assist in future completions.
