Reducing the duration will increase pressure because less air is being blown through. With boost pressure just being a measurement of resistance, being able to modify how far and long

Reducing the duration will increase pressure because less air is being blown through. With boost pressure just being a measurement of resistance, being able to modify how far and long the intake valves open should effectively change how and when the superchargers are reaching peak efficiency. The problem is there is too much overlap. The combustion process is still happening as usual, it's just when both the intake and exhaust valves are open, it's open for too long and reduces pressure. Getting more pressure built up on the intake side should allow more air to be pressurized in the combustion chamber when the intakes do open. Sorry if I'm talking in circles, I'm just trying to hit all the angles.
