Most of the water comes out the first of the three hoses. This is why I imagined that a system designed to dribble slowly, despite higher pressure (as I think someone said the Rain Bird system does) would in fact deliver a same or similar volume at the LAST emitter along a 200' line as it delivers at the first emitter.
Somebody said these systems can have fairly LONG lines with all emitters doing their jobs. I think some pressure would be needed in order to accomplish this.

In the diagram in my post above (#44) you'll see the Rainbird product (as well as the other similar branded products) have pressure compensating technology that ensures even distribution. If the "soaker hoses" you mention you used, do not have that - it's apples and oranges.
