I have a long, narrow planting area that I think would be a good place
to use a soaker hose. I tried one, the area at the head end got
flooded, at the distant end got very little water. I used pull
pressure from the hose bib, it seemed to me that the hose should carry
the water and that the amount leaking out should only be affected by
the porosity.

It's also affected by pressure, but that shouldn't be much different at one
end than the other. 7 feet of elevation is a 3 psi pressure difference.
