Courtesy runner question

[reccer]

David Emerling said a while back:

The DP bats and gets on base. Coach asks for time and wants the FLEX to run for the DP. Since the flex is the pitcher, the coach then wants a courtesy runner for his pitcher. Legal? Yes!

----------------------------------------------

However, in reviewing Emily's Cactus ump slides, she says:

A courtesy runner must run for the batter who hit the ball - not a sub for that batter

-------------------------------------------------------------------------
I will have this scenario this weekend in a tourney with a slow DP and my pitcher being the flex.

Is there a conflict between David and Emily's comments?

If David is correct, seems that all this is costing me is removing the DP one time from the line-up. Further, I seem to be able to do this a second time and although it will remove the DP from the game, the flex (pitcher) has not been affected and my CR still has entry rights for any position.

So, again assuming this is correct, here is how I am reporting to the umpire:

"Blue, that is my DP on base, I am going to drop down to 9 and insert my flex into the batting lineup. Since my flex is the pitcher, I am going to insert a CR for her."

Please let me know what you think, especially the part where I am discussing with the ump what is going on.
