Hello Marvin, You can also set up the processing method with as many decimal places, and then add decimal places to the Results Table in the Table Settings for the Expected RT column. 

Hello April, thanks for your comment. Actually the expected RT in the "integration parameters" after display the peak review is fixed at 2 decimal places. It would be much better that the number is shown in 3 decimal places.

3 decimal places are better for the RT Error % in the report table
