While I have never used a manometer in this method, I would also think that 
the end result would be the same. Pressure, Air Velocity, and Air Volume are 
all related. With a unisyn or similar device you are measuring the air that 
is being pulled in by the intake stroke of the piston. With a manometer you 
would be measuring the pressure created by the intake stroke of the piston, 
that pressure will be lower than atmospheric pressure due to the increasing 
volume of the cylinder. The air flowing into the carb, and the manifold 
pressure are flip sides of the same coin.

Its adjusting by differential pressure rather than adjusting for equal air 
flow.
