You don't indicate _how_ DBase III is calculating the averages or in what manner they are in error. It could be that you simply need to provide more accuracy in your field definition that you are using for the calculation. Or, you may need to carry the total points and count of games/whatever in separate fields and calculate the average each time you update one of those two fields. On the other hand, you may have a flaw in how you have defined the calculation.
