Does pressure matter if the flow rate is correct.
Say you have 300PSI, and you adjust the portafilter exit hole to give
you 2 ounces in 20 seconds, does the pressure really matter (try to
ignore some obvious concerns)?
I suspect it would not matter as the pressure differential would give you a
net same result. This however is just a speculation on my part, taste is
the best gauge.
Good speculation! The resistance of ball valve will add to the
resistance of the coffee: GRAND RULE OF PRESSURE in any coffee
machine: Same Flow = Same Pressure (valid for vibe&rotary+lever).
