A method for performing a calculation operation to grade and catalog the repeatability of an author's technical or instructional publication or some sub-portion thereof, comprising: a first step of collecting data from a user or users with experience in said publication's replication; a second step of converting the elements of the data to numerical quantities; a third step of calculating a weighting function for that user or users and a weighting function for the author; a fourth step of multiplying elements or subsets of the data by a weighting function that may amplify or diminish the value of the data; a fifth step of aggregating the weighted subsets of data into one or more values; and a sixth step of weighting and averaging the data with historical data, if any.
