No they don't. Both triple stage boosters and annular boosters increase signal because the are more restrictive. What is "correct" is to reference the booster signal required to the vacuum generated by the engine. Again stick a Dominator (1050) on a 318 and tell me all about atomization when you don't create enough vacuum to actually lift the fuel up through the main well and out to into the booster channel.
Triple stage Boosters actually double the depression by multiplying the depression created by the initial booster.
Here's none other than John Kaase clearly showing the pulsations that take place in a manifold. What do you think is pushing his finger back towards the carbs? Look at all that "atomized" liquid fuel on the walls and runners making its way to the intake valve..........

What do you think those pulsations will do to carb signal? What do think all that black **** on the underside of the air cleaner is and how does it get there?
