Totally agree, however if the concept isn't understood it morphs to the email that started this thread. 400 gpm through old 4" or 6" is a bigger problem.
The right way is to calculate to the flow, get the information to do it right. If it is a single-feed loop and you are on the remote end of that loop from the supply and the test, you need to account for the loss.
