In Ponemah v6.x, two methods exist to generate Excel sheet Reports 

• Export Data in Idle mode
• Save Derived Data/Save Marks Section from Review

When you open these Excel sheets, all derived parameter values are rounded by 2 decimal precision. But if you double click on the cell it shows the actual value.

There will a difference (in decimal points) in the actual value of derived parameters between these two Excel sheets

• Excel sheets created from “Export Data in Idle mode”: shows the actual value (without any decimal truncation)
• Excel sheets created from “Save Derived Data/Save Marks Section from Review”: shows the truncated value with the defined precision (4 will be the default precision if the parameter precision is not defined in the Algorithm Attribute)
