Hi steve,
If I understand correctly, you want to calculate the response time between visitor and operator. And if there are more than one visitors between two operators, we should calculate the first visitor. After testing the issue in my local environment, please
refer to the following steps:
In the design mode, click the menu” Report”>>”Report Properties”>>”Code” tab. Then place the code below in the section:
Dim shared AA As String 
Dim shared CC As Date
Dim shared DD As Date
Public Shared Function getPrevious(Person as String,Item As Date) As Integer
  If (Person="operator") Then
     DD=Item
  End If  
  If (Person=AA) OR (Person="operator")  Then
  Else
    AA=Person
    CC=Item
  End If     
  If (Person="operator") Then
       AA="nothing"
       return DateDiff("s",CC,DD)
  End If
 End Function
Right-click the times (response time) column to insert a column right of it.
Modify the expression of the new cell as follows:
=code.getPrevious(Fields!Person.Value,Fields!times.Value)
The following screenshot is for your reference:
If you have any other questions, please feel free to ask.
