This table presents the time spent making entering formulae and correcting errors. Each of the columns numbered from 1 to 8 represent a participant in the user testing.
The activities are: drawing, which is drawing strokes; grouping, making regrouping squiggle-selects, or looking for grouping errors; recognition, using the pop up menu to correct recognition errors, or looking for character recognition errors; and parsing, waiting for the parser.
