Based on the math behind the method (to be reviewed below), the more returns, the smaller the contribution of extraneous elements to the reading and, therefore, the greater the accuracy. Another benefit to using this app is that it automatically generates a report for you upon submission. 12. 0000000731 00000 n This should form an S-shaped curve with a relatively flat portion at its center. endstream endobj 107 0 obj <.
